Question

What is the polarizing angle of a medium of refractive index 1.732?

Answer 1

The refractive index of the denser media is 1.732. Calculate (i) thepolarizing angle of medium,(ii)theangle of refraction. (ii) At thepolarising angle, the reflected and the refracted ray are perpendicular to each other.

Answer 2

Given :

A medium of refractive index 1.732 .

To Find :

The polarizing angle .

Solution :

We know , tangent of polarizing angle is equal to the refractive index .

Let , polarizing angle be $\theta$ .

So ,

$tan\ \theta=1.732\\\\\theta=tan ^{-1}\ 1.732=tan ^{-1}\ \sqrt 3\\\\\theta=60^{\circ}$

Therefore , the polarizing angle of a medium of refractive index 1.732 is $60^{\circ}$ .
