Light passes through a vacuum

Light is absorbed by a black body

A light source travels at a high velocity

Light is reflected off of a glass window

Correct answer:

Light is reflected off of a glass window

Explanation:

Light is polarized when it is all oscillating in the same direction. This effect occurs when light is reflected. Polarization can occur through refraction, however if light is passing between mediums with the same index of refraction, the light will not refract.
