GCSE Physics - Water Waves - Shallow to Deep Water
 
05:32
This tutorial is about how waves can speed up or slow down when then enter a material with a different optical density, or when water waves enter regions of different depths. This change of velocity can cause the waves to change direction - this is called REFRACTION. Subscribe for more physics tutorials like this: http://bit.ly/Subscribe-Physics-Ninja Water waves will refract when then move from shallow to deep water causing them to speed up. As a result, their wavelength will increase and the refracted ray will 'SPEED AWAY' from the normal line. Remember that the wavefronts are always at 90 degrees to the ray. Use 'RNAR' to work through the steps: 1. Ray (incident ray) 2. Normal (line perpendicular to surface where the ray enters) 3. Angles (label the angle of incident and angle of refraction) 4. Use the refraction rule "SPEED AWAY" to determine which direction the refracted ray will bend. Quick question: During refraction, the wavelength and the speed of the wave changes. What does NOT change about the wave? (Answer... the frequency of the wave does not change) So why do waves get faster in deeper water? The answer is a bit complex, but here is an explanation posted at the Illinois Department of Physics: 1. For a shallow fluid, the motion of the fluid is mostly side-to-side. 2. In order to accumulate more fluid in one place (to make the crest of the wave), each little bit of fluid must travel a little farther than it would have to in deeper water. 3. When a wave passes, the bits of fluid (if you could watch one at a time) travel in ellipses. For shallow water, the ellipses are stretched out horizontally, and in very deep water, they are very nearly circular. 4. So for a wave of the same height (top to bottom of the ellipse), the bits of water must travel farther in the shallow tray than the deep tray. 5. Because the waves of the same height in shallow and deep water exert the same pressure differences due to gravity to get the water moving (although the motion is different due to the fact that the bottom is there), similar forces push and pull on the water. 6. To get the water moving farther and faster with the same force takes a longer time for each push, and hence a slower speed for the wave which travels in the shallow water.

Interference of Waves | Superposition and Interference in light and water waves | Physics
 
03:53
Interference of Waves | Interference and superposition explained in light and water waves with animation | Interference of waves in two dimensions | Physics The phenomena of the light which undergoes refraction and reflection by be explained by the 2 theories of light. They are corpuscular and wave theory of light. But some of the other phenomena such as interference and diffraction can only be explained by wave theory of light. We know that 2 or more wave, motions travel in space at the same time. Sometimes these 2 wave motions combine to and some physical effects take place. Inference is once such physical effect. When 2 or more waves cross each other in the same medium, they both interfere and accident takes. This accident is known as interference of waves. Interference is the combine effect of the disturbance caused by the each individual wave at the same place and at same time. This effect can be understood from the principle of superposition of waves. Principle Of superposition of waves: To understand this concept of the superposition, let's understand some of the examples. When we drop a pin in a tank, we see some circular waves. When other another pin is dropped, we see some more waves. These waves travel in the same tank and some or the other time these superimpose on each other. The resultant wave would have amplitude which is the sum of the displacement due to the individual waves. " The principle of superposition of waves states that when two or more waves travel through the same medium simultaneously, the resultant displacement at any point is the vector sum if the displacement due to the individual waves." In our case the pin is dropped in a ripple tank with 2 pins. If Y1 is the displacement caused at a point due to the first source and Y2 is the displace cause by the 2nd source, then the over displacement R at the point of interference would given by R=Y1+Y2 When both the sources have the same amplitude which then Y1,Y 2 would be equal to Y. When Y1 is due the crest or trough and Y2 is also due a crest or trough the resultant would be the maximum and when Y1 is due to a crest and Y2 is due to a trough or vice versa, the displacement would be minimum. When maximum displacement takes place it's called constructive superposition and when minimum displacement takes place it's called the destructive superposition. In constructive displacement, a maximum displacement curve is produced. Thus, when constructive displacement occurs then the phase difference between the waves would be ZERO or a multiple of 2π. When minimum displacement occurs, wave super impose destructively, the phase difference of the waves would be π or an odd integral multiple of the π. Interference of waves: When superposition of waves occurs, they could be constructive or destructive. This physical effort observed as a result of the superposition of waves is called interference. "The physical effect of the superposition of waves from the sources vibrating with the same frequency and amplitude is called the interference of waves. The physical effect is in the form of vibrations in the amplitude of resultant wave in a given potion of the medium" Interference is a special case of superposition of waves which originate from different sources but have the same amplitude, same frequency.

INTERFERENCE of Light - YOUNG'S DOUBLE SLIT Experiment | explained in HINDI
 
14:34
In this Physics video lecture in Hindi for class 12 we explained interference of waves and Young's double slit experiment. Interference of light is a special phenomenon reflecting the wave nature of light. Due to interference of light two waves interfere with each other and where crest and crest or trough and trough meet amplitude of light becomes very large and we say, there happens constructive interference. Otherwise, when crest of a wave and trough of another one meet, they cancel the effect of each other and we say, there happens destructive interference. The double slit experiment is a famous experiment conducted by Thomas Young where he used one source of light passing through two different slits and produced image on a screen behind. A very interesting pattern was found on the screen. There were several bright and dark patches which are known as fringes. This happens due to the wave behaviour of light and a special behaviour of waves, i.e., interference. ★★★★★★★★★★★★★★★★ A special thanks to Derek Alexander Muller, creator of YouTube channel 'Veritasium'.

Uses principles discovered in the science laboratory as a basis for interpreting the characteristics of water waves and wave motion on the ocean surface. Identifies wind as the most common source of a wave's energy, and points out that observation of water waves in a tank reveals that the particles in a wave describe circular orbits of a size inversely related to depth. Shows that waves are also caused by applying energy to the water's container, as happens in nature when an underwater earthquake alters the ocean floor, producing giant seismic waves.

Synthesized field of measured wave spectrum showing reflected waves against breakwater in Malaga
 
00:11
This is a movie of synthetic data, which is generated from real measurements. Data was collected with a 1 MHz AWAC, which was located in front of the breakwater in Malaga, Spain. What you are seeing a an interference pattern from incident waves from the southeast and reflected waves from the southwest. If you focus on the crests and troughs you will see that these directions hold true. The fascinating effect is that the wave field, as a whole, appears to be propagating from the south (which also happens to be the breakwater orientation). It is not so surprising that the estimated "mean direction" for the waves is from the south as well. In short, care must be taken when interpreting processed wave data ;-) A paper describing the details of measurement and the physics can be found here : http://www.nortek-as.com/lib/bibliography/resolving-transformed-wave-diretions-near-coastal

Constructive and destructive interference in water waves Video 2 of 4
 
01:30
One plus one equals two. That is true in understanding how one wave crest interact with another wave crest of the same phase, which in common terms is in sync. When out of sync, such as one wave crest meeting a wave trough, one plus negative one equal zero. This is the essence of constructive and destructive interference in wave dynamics. Understandable when presented as in above, what is difficult is in understanding how two or more wave propagations interact at specific points of space in their interference zone. The tool to do this is Huygens’ construction, but although graphical in nature, it is a major bugbear of most students in understanding wave dynamics. Because students could not visualize the cross interaction lines on their Huygens’ construction, and determine which nodes are constructive interference and where are the destructive ones. The intellectual leap needed to overcome the last point is crucial to understanding wave dynamics and using it to solve problems in hydraulics, design of breakwater location, and how earthquake waves move through earth. The four videos in this series features waves associated with high tide coming to shore at Labrador Park, Singapore that manifest in clear constructive and destructive interference zones. Waves breaking up into foamy water as it nears shallow land can also be observed. Hopefully, the videos would be useful for students to visualize wave dynamics and researchers seeking to understand the hydrology of Labrador Park in Singapore.

Chilean Tsunami
 
00:48
Numerical simulation of the February 2010 Chilean Tsunami for the West Coast of Canada. This animation was generated by the Institute of Ocean Sciences Tsunami Numerical Model developed by Dr. Isaac Fine under contract to Dr. Richard Thomson of Canada's Department of Fisheries and Oceans Institute of Ocean Science. The model is a "regional tsunami model" based on the equations of motion for linear shallow water waves and specified forcing at the oceanic boundary of the model domain. For this particular run, the model was forced using the NEPTUNE BPR 1027S sea level record spanning the period 21:24UTC February 27 to 02:15UTC February 28, 2010. The model has a 2400 x 2800 grid domain (latitude 47º N-51º N; longitude 129º W-122º W) with a corresponding grid spacing of approximately 180 m x 160 m. The sea level simulation for the British Columbia coast covers a duration of 6 hours and includes the initial propagation of the tsunami waves into the Strait of Georgia from the south via Juan de Fuca Strait and from the north via Johnstone Strait. The difference between the model and the observations is least at NEPTUNE site 1027S since the model is initialized using sea level elevations from this location. Both incoming and reflected waves appear in the simulation; dark blue denotes wave crests and bright white wave troughs. Incoming waves are strongly affected by refraction over the continental slope and shelf, causing the waves to become increasingly parallel to the shoreline as they approach the coast. The reflected waves along the outer coast are much more complicated than the incoming waves due to the added effects of topographic and coastline scattering.

What is BREAKING WAVE? What does BREAKING WAVE mean? BREAKING WAVE meaning & explanation
 
04:04
What is BREAKING WAVE? What does BREAKING WAVE mean? BREAKING WAVE meaning - BREAKING WAVE definition - BREAKING WAVE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In fluid dynamics, a breaking wave is a wave whose amplitude reaches a critical level at which some process can suddenly start to occur that causes large amounts of wave energy to be transformed into turbulent kinetic energy. At this point, simple physical models that describe wave dynamics often become invalid, particularly those that assume linear behaviour. The most generally familiar sort of breaking wave is the breaking of water surface waves on a coastline. Wave breaking generally occurs where the amplitude reaches the point that the crest of the wave actually overturns—though the types of breaking water surface waves are discussed in more detail below. Certain other effects in fluid dynamics have also been termed "breaking waves," partly by analogy with water surface waves. In meteorology, atmospheric gravity waves are said to break when the wave produces regions where the potential temperature decreases with height, leading to energy dissipation through convective instability; likewise Rossby waves are said to break when the potential vorticity gradient is overturned. Wave breaking also occurs in plasmas, when the particle velocities exceed the wave's phase speed. During breaking, a deformation (usually a bulge) forms at the wave crest, either leading side of which is known as the "toe." Parasitic capillary waves are formed, with short wavelengths. Those above the "toe" tend to have much longer wavelengths. This theory is anything but perfect, however, as it's linear. There have been a couple non-linear theories of motion (regarding waves). One put forth uses a perturbation method to expand the description all the way to the third order, and better solutions have been found since then. As for wave deformation, methods much like the boundary integral method and the Boussinesq model have been created. It has been found that high-frequency detail present in a breaking wave plays a part in crest deformation and destabilization. The same theory expands on this, stating that the valleys of the capillary waves create a source for vorticity. It is said that surface tension (and viscosity) are significant for waves up to about 7 cm (3 in) in wavelength. These models are flawed, however, as they can't take into account what happens to the water after the wave breaks. Post-break eddy forms and the turbulence created via the breaking is mostly unresearched. Understandably, it might be difficult to glean predictable results from the ocean. After the tip of the wave overturns and the jet collapses, it creates a very coherent and defined horizontal vortex. The plunging breakers create secondary eddies down the face of the wave. Small horizontal random eddies that form on the sides of the wave suggest that, perhaps, prior to breaking, the water's velocity is more or less two dimensional. This becomes three dimensional upon breaking. The main vortex along the front of the wave diffuses rapidly into the interior of the wave after breaking, as the eddies on the surface become more viscous. Advection and molecular diffusion play a part in stretching the vortex and redistributing the vorticity, as well as the formation turbulence cascades. The energy of the large vortices are, by this method, is transferred to much smaller isotropic vortices. Experiments have been conducted to deduce the evolution of turbulence after break, both in deep water and on a beach.

Wave Pool for Surfing in Asia

Free video about Wave pool surfing. This free video was created for you by http://epsos.de and can be used for free under the creative commons license with the attribution of epSos.de as the original author of this Wave pool surfing video. Thank you for supporting the creative commons movement !! Wave pool is artificial wave pool is causing normal water park to be waves. The wave pool is relatively low height of the waves and waves of a high altitude. Among the more threatening waves fall in a region where the wave that is, a sudden broadening of the wave pool section of the wave count, especially. So, should pay attention to this part. However, this is similar to or higher 2m wave height only significant function. In other words, the tens of cm or larger waves of around 1m does not work. A wave pool is a swimming pool where artificial waves are created. Thus the bather is mediated an experience that the swimming in the sea comes closer than in classical swimming pools. There are several designs of wave machines. What is each used depends in particular on the size of the bath and the desired size of the shaft. In smaller tanks, compressed air is blown onto the water surface, so there is no pendulum used is water. In contrast, displacement body or swing wings are used for medium wave sizes mostly, which have a pneumatic or mechanical drive. Another possibility is "accordion-like" bellows, which compress air through pressure and thus express water or reopen and thus collect water. For large bathrooms finally mostly a large amount of pendulum water is supplied from a few meters higher ground reservoir suddenly in the wave pool, which creates the wave by fast displacement. The pendulum water is then pumped back continuously from the tank into the reservoir. This technology also wave heights of up to 3 meters can be achieved. In some wave pools even descending the breaking wave is with a surfboard possible. In systems with spherical water of the pool water level is lowered before the start of wave operation, so that the water does not overflow at wave operation. The Absenkwasser is either in the raw water Splash container or buffered in a separate container. Wave pools provide the supervisory staff and swimmers before increased demands. Due to the continuous movement of the water surface, the changing optical refraction of the surface and reflections, it is difficult to identify people in need. Also, some swimmers overestimate their abilities under the difficult conditions with waves swimming. Therefore, the operator of the wave pools dispense generally to wave height. A wave machine is used to generate artificial water waves. There are wave machines for the generation of traveling waves (use in wave pools, to water aerobics, swimming training or physical therapy ) and wave machines for the production of regular, stationary waves ( surfing ). In addition, wave machines are in tow tanks and Seegangsbecken of shipbuilding research institutions used artificial seaway to produce. On the deep side of a pool is rhythmically displaced by the displacement body, pivoting wing, piston or air pressure water. Through a crack in the lower part of the basin, the water is then pushed into the swimming area. There the waves, expiring at the flatter part of the basin and by the arising wave flashover, the marine coastal famous surf sounds produce. The surfboard or surfing is a sport that involves planar water with surfboard on the crest of a wave as it carries the surfer practicing this towards the coast. If the person who practices the sport makes it right on the table can be classified into two groups surfing: the longboarding and shortboarding. The major differences between the two methods is the design of the table and obviously in the style of surfing waves. There is also surfing often associated with big wave surfing, in which a private motor vehicle, such as a personal watercraft, tows the surfer being a leader in the area of the wave in the direction of the coast, helping to achieve the fastest speeds with the wave higher than the surfer could not achieve by itself. The surf related sports such as paddleboarding, the Stand Up Paddle and sea kayaking do not require waves, and other derivative sports that rely on wind power as are windsurfing and surfing kite, but can also be tables for cabalcar waves. Today, the sport of surfing represents revenues of billions of dollars in the industry sector, especially in the markets of surfing clothes and fashion.

As discussed by feynman, 'there are, in fact, an infinite number of different possibilities for [energy density] and [flux], so far no one has thought experimental way to tell which is right!' 1 nov 2012 what wave amplitude how measure it, determines the a 25 2011. The relationship between the energy and amplitude of a wave why intensity light(wave) is proportional to square its ( read ) physics video by brightstorm. Where d is frequency, wavelength, amplitude and wave speed. Loudness is a perceptual response to the physical property of intensity. Amplitude, frequency, wavenumber, and phase shift are properties of waves that govern their physical behavior. Graphing a wave when drawing or looking at on graph, we draw the as snapshot in time for longitudinal wave, such sound amplitude is measured by maximum displacement of particle from its position equilibrium. The maximum height observed in the wave is called as amplitude. Another thing scientists measure in waves is the wave's amplitude or height. The amplitude of a wave is measured as the height from equilibrium point to highest crest or. Sound waves in air are longitudinal, pressure it is an objective quantity associated with a wave. The wavelength,, of a wave is the distance from any point on one to same next along 24 apr 2015. Together, these properties account for a wide range of phenomena such as loudness, color, pitch, diffraction, and there are many that scientists use to describe waves. As a general rule the larger amplitude, greater intensity, louder sound. Amplitude is the distance from rest position to crest which half vertical a trough. That is, how do you measure the height or amplitude of a wave? Look at these diagrams and see if can figure out good definition for poster from that link is saying work done by spring (that's hooke's law there f k x ) equal to potential energy (pe) maximum displacement,; This pe comes kinetic (ke) integral over range 0 (minimum displacement) (maximum it effectively defined way because it's simplest form satisfies relevant conservation equation. The amplitude of a variable is measure its change over single period. What exactly do we mean by a wave's 'amplitude'. Tutorvista physics a

#Rarefaction #audioversity ~~~ Rarefaction ~~~ Title: What is Rarefaction? Explain Rarefaction, Define Rarefaction, Meaning of Rarefaction Created on: 2018-11-11 Source Link: https://en.wikipedia.org/wiki/Rarefaction ------ Description: Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves , rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave . Rarefaction waves expand with time ; in most cases rarefaction waves keep the same overall profile at all times throughout the wave's movement: it is a self-similar expansion. Each part of the wave travels at the local speed of sound, in the local medium. This expansion behaviour is in contrast to the behaviour of pressure increases, which gets narrower with time, until they steepen into shock waves. ------ To see your favorite topic here, fill out this request form: https://docs.google.com/forms/d/e/1FAIpQLScU0dLbeWsc01IC0AaO8sgaSgxMFtvBL31c_pjnwEZUiq99Fw/viewform ------ Source: Wikipedia.org articles, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.
