A cubic container is filled with a liquid whose refractive index increases linearly from top to bottom. Which of the following represents the path of a ray of light inside the liquid ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
a.
Since the refractive index is changing, the light cannot travel in a straight line in the liquid as shown in option (c) and (d). Initially, it will bend towards normal and after reflecting from the bottom it will bend away form the normal as shown below

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 :
