Question

describing electromagnetic waves
describe how electromagnetic waves are formed and travel through space.

Explanation:

Electromagnetic waves are formed when charged particles accelerate. This acceleration causes changing electric and magnetic fields which are perpendicular to each other and to the direction of wave - propagation. These fields self - regenerate and travel through space as electromagnetic waves without the need for a medium.

Answer:

Electromagnetic waves are formed by the acceleration of charged particles. The changing electric and magnetic fields, which are perpendicular to each other and to the wave's direction of travel, self - regenerate and move through space without a medium.
