Question

A ray of light travelling in air falls on a surface whose refractive index is 1.5. If the angle of incidence is 300, find the angle of refraction.

Please give step by step solution ​

Answer 1

Answer:

We know that refractive index of air is 1

Here the incidence angle is i=53°

Using snell's law n air sini=n glass sinr

sin53=1.6sinr

$\frac{4}{5} =1.6sinr$

r=30°
