The refractive index of a medium is square root of 3. What is the angle of refraction, if unpolarised light is incident on it at the polarising angle of the medium?

answered-by-expert Expert Answer
The relation between polarization angle θp and refractive index μ is given by
tan θp = μ
 
hence θp in this problem is tan-1√3 = 60º.
 
if incident angle is 60º then angle of refraction r is obtained from sin(r) = sin 60º / √3 = 1/2
 
hence angle of refraction is 30º
