The refractive index of medium is 3\sqrt{3}. If the unploarized light is incident on it at the polarizing angle of the medium, the angle of refraction is :

A

600

B

450

C

300

D

00

Answer

300

Explanation

Solution

Using tanip=3\tan i_{p} = \sqrt{3}

ip=tan1(3)=60º\therefore i_{p} = \tan^{- 1}(\sqrt{3}) = 60º

As r=90ºipr=90º60º=30ºr = 90º - i_{p}\therefore r = 90º - 60º = 30º
