Electromagnetic radiation moving through space with the speed of light consists of oscillating
A) electric and magnetic fields moving in opposite directions along the same line in space.
B) magnetic fields that over time and distance change to oscillating electric fields and then back to magnetic fields in a continuous manner.
C) electric and magnetic fields with the same frequency and wavelength and traveling in the same direction.
D) electric fields, with magnetic fields occasionally accompanying them, moving in the same direction.

Question

Quizplus · Accepted Answer

Electromagnetic radiation consists of electric and magnetic fields that oscillate at the same frequency and wavelength, and they travel together in the same direction through space. This is a fundamental principle of electromagnetism as described by Maxwell's equations.
