Question

A ray of light is incident obliquely on a glass slab. Draw a ray - diagram showing the path of the light ray. Clearly mark angle of incidence, angle of refraction, angle of emergence and lateral displacement of the ray. Give a formula to find refractive index of glass slab in terms of angle of incidence and angle of refraction.

Answer 1

Refractive index =angle of incidence /angle of refraction

Answer 2

Answer:

the ray will be reflected at an angle equal to the angle of incidence
