Question

6. (2 pts.) Suppose that sunlight strikes the flat horizontal surface of a car hood that is coated with a transparent layer of car wax (n = 1.54). At what angle of reflection is the reflected light completely (100%) horizontally polarized? Show your work. Thought question (not for credit]: In order to block as much of the reflected sunlight as possible from reaching your eyes, you should wear polarized sunglasses that have polarizers with what orientation?

Answer 1

6)

Using Brewsters angle formula,

C\ tanᎾ = 11

Where theta is the angle of reflection. (Angle of reflection = Angle of incidence).

O = tan-1G1) = 0.576 degree

Inorder to block as much as sunlight from reaching the eye, the polarizers must be oriented at 90 degree angle with each other.
