The polarization of a light wave is determined by the direction
A) of the oscillating electric field.
B) of the light's velocity.
C) of the fluorescent tube used as a light source.
D) perpendicular to both the electric and magnetic fields.

Question

Quizplus · Accepted Answer

The direction of polarization of a light wave is determined by the direction of the oscillating electric field. This means that the electric field vector of the light wave oscillates in a specific direction, which determines the polarization of the light. The other choices are not related to the direction of polarization.
