A beam of "unpolarized" light
A) does not have any polarized waves.
B) contains a single light wave with a fixed polarization direction.
C) can be polarized by reflecting it from a flat surface.
D) has a polarization direction that is constantly rotating.

Question

Quizplus · Accepted Answer

Unpolarized light consists of waves vibrating in multiple planes. When it reflects off a flat surface, the light can become polarized, meaning the waves align along a common plane. This is due to the Brewster angle phenomenon, where light reflecting at a specific angle from a surface has its electric field vectors aligned, resulting in polarization.
