Question

state and explain the laws of refraction of light?

Answer 1

The two laws of refraction are:-

1.the normal , incident Ray and refrected Ray lie at same plane.

2.sini/sinr=constant
the ratio of sin of angle of incident with sin of angle of refraction is constant.

Answer 2

The law of refraction, which is generally known as Snell's law governs the behave of light rays as they propagate across a sharp interface between two transparent dielectric media.

laws of refraction states are...
1. the incident ray, the refracted ray and the normal to the interface of two media at the point of incidence all lie in the same plane.
2. For the light of a given color and for given pair of media, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.

sin i/ sin r = constant
