Question

A ray of light passing through a certain medium meets the surface separating the medium from air at 60 fegree and it just not refracted what is refractive index of the medium​

Answer 1

Answer:

In this case total internal reflection takes place due to which sin C=30°

SinC= 1/mu

1/2 = 1/mu

refractive index = 2 or 2/√3
