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

Refractive index of second material will be 1.41

Step-by-step 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* sin41.1=n_2* sin27.7`

`n_2=1.41`

So refractive index of second material will be equal to 1.4
