When a ray is incident on a medium of refractive index n at Brewsters angle, it gets:

A)  totally reflected

B)         totally absorbed

C)  circularly polarised

D)  plane polarised

E)  elliptically polarised

Correct Answer: D

Solution :

According to Brewsters 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.
