In electromagnetic waves, how are the electric and magnetic fields onented relative to the direction of propagation? a Perpendicular to each other and parallel to the direction of propagation b. Parallel to each other and the direction of propagation C. Parallel to each other but perpendicular to the direction of propagation d. Perpendicular to each other and the direction of propagation

The correct answer is d. Perpendicular to each other and the direction of propagation.<br /><br />In electromagnetic waves, the electric and magnetic fields are perpendicular to each other and also perpendicular to the direction of propagation. This means that the fields oscillate perpendicular to the direction in which the wave is traveling. This orientation allows the wave to propagate through space, with the electric and magnetic fields changing in a way that supports the wave's movement.
