An unpolarized beam of light is incident on a pane ofglass (n = 1.56)such that the reflected component coming off the glass is completely polarized.What is the angle of incidence in this case?
A)32.7 $\degree$
B)41.0 $\degree$
C)49.0 $\degree$
D)57.3 $\degree$

Question

Quizplus · Accepted Answer

The angle of incidence for which the reflected light is completely polarized is known as Brewster's angle. It can be calculated using the formula: tan(θ) = n, where n is the refractive index. For n = 1.56, θ = arctan(1.56) ≈ 57.3°.
