A ray of light travelling in a transparent medium of refractive index $\mu $, falls on a surface separating the medium from air at an angle of incidence of 45o. For which of the following value of $\mu $ the ray can undergo total internal reflection ?

Question

A ray of light travelling in a transparent medium of refractive index $\mu $, falls on a surface separating the medium from air at an angle of incidence of 45^o. For which of the following value of $\mu $ the ray can undergo total internal reflection ?

$\mu $ = 1.33

$\mu $ = 1.40

$\mu $ = 1.50

$\mu $ = 1.25
