Question

what
are
the law of refraction Deline refractive
index of a medium.
​

Answer 1

Explanation:

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.

Definition of refractive index:

The refractive index is the measure of bending of a light ray when passing from one medium to another.
