laws of reflection and refraction

The incident ray, refracted ray and the normal, all lie in one plane. The ratio of the sine of angle of incidence to the sine of angle of refraction is constant for the pair of media in contact. This is denoted by 1 m 2 and is refractive index of medium 2 (den..

Let us now see what happens when a ray of light is incident on the boundary separating the two media having different densities. A part of the light gets reflected and rest of the light changes its direction as it enters the second medium. The diagram shows how the light gets r..

The reflection at any plane surface is found to obey the laws of reflection. The laws of reflection are: The incident ray, the reflected ray and the normal at the point of incidence lie in the same plane. The angle of incidence is eq..

The incident ray, the reflected ray and the normal at the point of incidence lie in the same plane. The angle of incidence is equal to the angle of reflection..

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..

Refraction of Light - Light not only bounces off surface it goes through some of them often slowing down and changing direction in the process called refraction. It occurs at the point where light travels from one medium to another of different density. Refraction prod..
