Question

Green light is incident at the polarising angle on a certain transparent medium. The angle of refraction is 30° . Find
(i) polarising angle, and
(ii) refractive index of the medium.

Answer 1

The refractive angle can be given as :
$r=30°$

i_p​ = 90 − 30

i_p​ = 60°

 

The angle of polarization can be given as :

M = tan i_p​

M = √3 ​= 1.732
