I know that standard stuff that every textbook says about electromagnetic radiation. I know the different categories (x-ray, microwave, visible light, etc). I know the meaning of the words frequency and wavelength. I still don’t really understand what electromagnetic radiation IS or why objects emit it. I know that wavelength is the distance between the crests of the wave, but what ARE the crests?

A charged particle produces an electric field, a moving charged particle generates a magnetic field, and an accelerating charged particle emits electromagnetic wave; a propagation of electric and magnetic fields through space.
