Question

Consider a tank made of glass (refractive index 1.5) with a thick bottom. It is filled with a liquid of refractive index $\mu$. A student finds that, irrespective of what the incident angle i (see figure) is for a beam of light entering the liquid, the light reflected from the liquid glass interface is never completely polarized. For this to happen, the minimum value of $\mu$ is

Select the correct option:

A

$\frac{4}{3}$

B

$\sqrt{\frac{5}{3}}$

C

$\frac{3}{\sqrt{5}}$

D

$\left.\frac{5}{\sqrt{3}} \right\rvert\,$
