... 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. What are electrons and protons? An electron is ... pulls them together.An electron's motion depends on both the force on the electron and its velocity, which are often in different directions. What is a Force field? In physics, a force f...
