As they move through space, the vibrating electrical and magnetic fields of a light wave mustmove perpendicular to each other.

Question

Quizplus · Accepted Answer

This is known as the transverse nature of an electromagnetic wave. This is known as transverse wave motion, where the direction of the wave motion is perpendicular (at a right angle) to the direction in which the wave is traveling. In the case of a light wave, the electric and magnetic fields oscillate perpendicular to each other, both perpendicular to the direction of wave propagation.
