describe how electromagnetic waves are formed and travel through space.

Brief Explanations:

Electromagnetic waves are formed when charged - particles accelerate. This acceleration causes a changing electric field, which in turn generates a changing magnetic field. These changing fields are perpendicular to each other and to the direction of wave propagation. In a vacuum or space, these self - regenerating electric and magnetic fields travel as electromagnetic waves at the speed of light.

Answer:

Electromagnetic waves are formed by the acceleration of charged particles, which create changing electric and magnetic fields. These fields are perpendicular to each other and to the direction of wave propagation. In space, they travel as self - regenerating waves at the speed of light.
