question_answer

The angle of incidence of light is equal to Brewsters angle, then A reflected ray is perpendicular to refracted ray B refracted ray is parallel to reflected ray C reflected light is polarized having its electric vector in the plane of incidence D refracted light is polarized

A)   and  are true   

B)   and  are true

C)   and  are true

D)   and  are true

Correct Answer: C

Solution :

                 From Brewsters law reflected ray is perpendicular to refracted ray. The reflected ray so obtained is plane polarized having its electric vector in the plane of incidence.
