CBSEENPH12038435

The polarising, angle of a medium is 60°. What is the refractive index of the medium?

Solution

Given, 
Polarising angle for a medium = 60o 
Therefore, refractive index of the medium is given by Brewster's law. 

Thus , 
                     μ = tan ip    = tan 60o    = 3   = 1.732
