Question

Which of the following statements are correct for light incident at the Brewster angle on a transparent dielectric interface?

G1 Physics · Accepted Answer

At Brewster incidence, i(B)+r = 90°. Therefore the reflected and refracted rays are perpendicular. So A is correct. At this angle, the reflected p-polarized component vanishes, so the reflected beam is completely plane polarized. Thus B and D are correct. The correct Brewster relation for incidence from medium n₁ to medium n₂ is tan i(B) = n₂ ÷ n₁, not n₁ ÷ n₂. Therefore C is false. Correct answers: A, B and D.
