Question

What are the 2 laws of Refraction of light??​

Answer 1

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

Answer 2

The two laws of refraction of light 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.
