The refractive index of the denser media is 1.732. Calculate (i) the polarizing angle of medium,(ii)the angle of refraction.

Expert Answer
Here n=1.732
(i)According to Bewsters law, tan ip=n
Therefore polarizing angle ip=tan-1 n
=tan-1(1.732)
=600
(ii) At the polarising angle, the reflected and the refracted ray are perpendicular to each other.
Therefore angle of refraction r = 900 - ip
=900 - 600
=300
