When a ray is incident on a medium of refractive index n at Brewster's angle, it gets

A)  totally reflected              

B)  totally absorbed

C)  circularly polarized         

D)  plane polarized

Correct Answer: D

Solution :

                 According to Brewster?s law, when unpolarised light is incident at polarizing angle \[{{i}_{p}}\]on an interface separating a rarer medium from a denser medium of refractive index \[\mu \], such that then light reflected in the rarer medium is completely polarized.
