Question

A light ray is incident on air liquid interface at 45degree and is refracted at 30degrees what is the refractive index of liquid for what angle of incidence will be the angle between reflected ray and refracted ray

Answer 1

Refractive index=sin I/sin r
Refractive index of liquid with respect to air ,i.e.,n21=45°/30°
=3/2
=1.5
