How do waves behave? Badly? In this video we are going to look at how light and sound waves behave. Before we start, you should know that waves can be transverse or longitudinal. Transmission, reflection, refraction, diffraction, absorption and scattering are all typical wave behaviours. Reflection is when waves bounce off an object. Sound waves are reflected by hard, flat surfaces and is why we get echoes. You hear a delay between the original sound and the echo, because the echoed sound waves have to travel twice as far to reach your ears. Smooth surfaces, like glass and polished metal, reflect light in a regular way, so a reflection can be seen. Like a mirror, or seeing your face in a calm pond. Transmission is when waves keep travelling in the same direction through an object. Like light through a window. Absorption and reflection often go hand in hand for light waves. White light contains each wavelength - so all the colours of visible light. The colour of an object depends on which wavelengths of light it absorbs and which it reflects. White objects reflect all the light that hits them, and absorbs none. Black objects reflect none and instead absorb all the light that hits them. A red object absorbs all the wavelengths except the red, which is reflected. And a green object absorbs all the wavelengths except the green, which is reflected. Are the new people upstairs really noisy? If they carpet their floors, add curtains and furniture to the room then you’ll notice that they become much quieter. This is because some objects absorb sound waves. When sound and light waves pass across a boundary between two substances, like air and glass, they change speed. This is because the substances have different densities. The change is speed causes the waves to change direction, which is known as refraction. Because of refraction, things in water look closer than they really are and water appears shallower than it really is. And a straw in a glass of water looks like it bends at the surface, because the refracted light wavelengths make you think the straw is in a different place to where it actually is. When waves meet a gap in a barrier, they pass through the gap. They then spread back out after they pass through the gap - this is diffraction. The way the waves re-spread depends upon how big the gap is compared to the incoming wavelengths. We have diffraction to thank for loudspeakers. Sometimes waves depart from the expected path, and spread out in multiple directions. This is known as scattering. We have scattering to thank for making the sky appear to be blue. The white light coming from the sun hits the molecules in our atmosphere, which cause the shorter blue wavelengths to scatter out in all directions. So waves behave in a variety of ways, depending upon what material they hit.

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.

The Mini Ripple Tank is a great way to address the wave-energy standards and to teach about the properties of waves by showing how water waves behave. Ripple tank wave generators are such a wonderful way to demonstrate the principles of wave propagation, reflection, refraction, diffraction and interference, but they can be time consuming to set up and take down. This Mini Ripple Tank addresses these issues by providing a completely self contained device, requiring no set-up apart from the addition of water. Easy changing of wave frequency! Excellent for showing diffraction, 2 source interference patterns, refraction, and reflection. Great for small groups! It is small and portable, making it great for small group demonstrations or stations. http://www.arborsci.com/mini-ripple-tank

A ripple tank is placed above a mirror and a projection screen. A horizontal bar, whose frequency can be varied, taps the surface of the water and produces plane waves. The waves are incident on a barrier containing an adjustable opening. With a narrow single slit opening we see a plane wave emerge as a spherical wave on the other side of the barrier. This can be explained by the Huygens-Fresnel principle which states that each point in the slit forms its own spherical wavefront source. With a wider slit, more point sources arise, causing interference patterns due to the larger angles involved with a broader spatial distribution of these sources.

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.
