Which statement gives the relationship between the waves in the electric and magnetic fieldsin an electromagnetic wave?
A)They are in phase and parallel with each other in space.
B)They are 90 degrees out of phase but parallel in space.
C)They are in phase but perpendicular to each other in space.
D)They are 180 degrees out of phase and random in their inclinations to each other.
E)They are in phase but opposite in direction of motion.

Question

Quizplus · Accepted Answer

In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other and are in phase. This means that the peaks and troughs of the waves in the electric and magnetic fields occur at the same time and are oriented at right angles to each other. Choice C accurately describes this relationship. In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other and in phase, meaning they reach their maximum and minimum values at the same time and at right angles to each other.
