| A beam of light is incident on a glass plate at an angle of incidence 60∘. The reflected ray is polarized. The angle of refraction when the angle of incidence is 45∘ is
A. sin−1(√32)
B. cos−1(√32)
C. sin−1(1√6)
D. sin−1(1√3)
Please scroll down to see the correct answer and solution guide.
Right Answer is: C
SOLUTION
μ=tan 60∘=√3
sin isin r=√3⇒sin r=sin 45∘√3=1√6
⇒r=sin−1(1√6)
