Question

write the law of refraction explain the same with the help of ray diagram when a Ray of light passes through a rectangular glass slab​

Answer 1

$\huge\red{hey....}$

The laws of refraction of light are as follows-:

The incident ray. the refracted ray and the normal at the point of incidence all lie on the same plane.

The ratio of sin of angle of incidence to the sin of angle of refraction is a constant which is called the refractive index of second medium with respect to first medium...

Don't have diagram
