Which of the following statements best explains how electromagnetic (EM) waves propagate?

Question

Accepted Answer

The electric and magnetic fields in an EM wave are perpendicular to each other and to the direction of wave propagation.

Answer

In an EM wave, the electric field oscillates parallel to the magnetic field, and both propagate in the same direction.

Answer

The magnetic field oscillates along the direction of wave propagation, while the electric field is perpendicular to it.

Answer

Both the electric and magnetic fields oscillate along the direction of wave propagation in an EM wave.
