refraction and reflection

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..

Refraction of Light - 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..

a m g represents refractive index of glass with respect to air then Similarly if refraction occurs from denser to rarer medium or The above expression is an important result of the principle of reversibility of light which states that when a ray of light after suffering a large ..

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..

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 land surfac..
