Question

A ray of light passing through air is incident on the surface of a transparent material at an angle of incidence 30 degree.which of the following statements is correct if the angle of refraction is 50 degree​

Answer 1

Answer:

hope it's helpful to you!

Explanation:

Snell's Law of refraction gives the relation between the incident and refracted light at the interface of two media, which is given by

μ

=

sinr

sini

The initial medium is air. Thus μ

=1

Given incidence angle i=45

and refraction angle is 30

o

By Snell's law, μ

Answer 2

Answer:

The refractive index of the transparent material with respect to air is less than 1
