Question

The angle of incidence of light is equal to Brewster's 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 plane of incidence (D) refracted light is polarized

• A. (A) and (D) are true
• B. (A) and (B) are true
• C. (A) and (C) are true
• D. (B) and (C) are true

Answer 1

Answer: (C)

(A) and (C) are true

Answer 2

By Brewster's law reflected ray is perpendicular to refracted ray.

The reflected ray so obtained is plane polarised having its electric vector in the plane of incidence.
