Question

Quizplus · Accepted Answer

Electromagnetic waves are produced by electric charges in accelerated motion, which result in changing electric and magnetic fields that propagate through space. Choices A and B are incorrect because they involve electric charges moving with constant velocity or at rest, respectively, which do not produce changing electric and magnetic fields. Choice D is incorrect because it includes all three answers, but only choice C is correct.
