reflection and refraction of sound

Like light, sound waves also obey the laws of reflection and refraction. For sound waves to reflect, we need extended surface or obstacle of large size. For example, the rolling of thunder is due to successive reflections from clouds and l..

When sound is incident on a solid or a liquid surfaceit bounces off the surface like light rays. Sound waves also obey the laws of reflection and refraction. For sound waves to reflect, we need extended surface or obstacle of large size. F..

IO incident ray OR l reflected ray OR refracted ray The diagram shows how the light gets refracted when it is traveling from one optical medium to another. Like reflection, refraction of light takes place according to certain laws. Before we state t..

Bats and dolphins can detect the presence of an obstacle by hearing the echo of the sound produced by them. This process is called sound rangin..

Let us now see what happens when a ray of light is incident on the boundary separating the two mediums having different densities. A part of the light gets reflected and rest of the light changes its direction as it enters the second mediu..

In the previous chapter we have seen how light gets reflected when it is incident on a surface. Now let us see what happens when a ray of light traveling from one medium to another medium of different densit..

Introduction - In the previous chapter we have seen how light gets reflected when it is incident on a surface. Now let us see what happens when a ray of light travelling in one medium enters another medium of different optical density. It is a matter of common experience that a spoon plac..

: Curved surfaces can reflect sound waves. This reflection of sound waves is used in auditorium to spread the waves uniformly throughout the hall. Reflection of sound waves is done by using Sound Boards. The speaker is located a..
