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:

A

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

B

$$\frac{4}{3}$$

C

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

D

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