explain how electromagnetic waves are produced.

Brief Explanations:

Electromagnetic waves are produced when charged particles accelerate. As the charged - particle moves with acceleration, it creates a changing electric field. A changing electric field in turn generates a changing magnetic field. These changing electric and magnetic fields are perpendicular to each other and also perpendicular to the direction of wave propagation, forming an electromagnetic wave.

Answer:

Electromagnetic waves are produced by accelerating charged particles which create changing electric and magnetic fields.
