Quizplus · Accepted Answer

None of the statements are true. Maxwell's equations apply to fields that vary in time, electromagnetic waves are transverse waves, the electric and magnetic fields are in phase in an electromagnetic wave, and the electric- and magnetic-field vectors have different magnitudes in an electromagnetic wave.
