Question

A ray of light hits the surface between air and an unknown material at an angle A of 41.1°. It travels through the unknown material at an angle B of 27.7° relative to the vertical. What is the index of refraction of the material?

Answer 1

Answer:

Refractive index of second material will be 1.41

Explanation:

It is given refractive index of first material, that is air $n_1=1$

Angle of incidence = 41.1°

Angle of refraction from second material = 27.7°

We have to find the refractive index of second material.

Now from Snell's law $n_1sini=n_2sinr$

$1\times sin41.1=n_2\times sin27.7$

$n_2=1.41$

So refractive index of second material will be equal to 1.4
