Basics of Electromagnetism

same kind of wavy disturbance that repeats itself over a distance called the wavelength.

The wave, or "disturbance," is in an invisible thing called the electric force field.

To understand electric forces, we have to learn something about charged particles like

electrons and protons. Without these charged particles, there can be no electric

force fields and thus no electromagnetic waves.
