Answer:

An electromagnetic wave can be created by accelerating charges; moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light.

Explanation:

Answer:

Sample Response:

The source of electromagnetic waves are charged particles that begin to oscillate when acted upon by a disturbance. These oscillating particles create an oscillating magnetic field. The oscillating magnetic field then creates an oscillating electric field, and an oscillating electric field in turn creates an oscillating magnetic field.
