The Nature of Electromagnetic Waves
... Electromagnetic waves are produced by the vibrations or oscillations of charged particles. The frequency is the number of times a particle vibrates per second. The vibrations produce a wave with a wavelength inversely proportional to the frequency (one vibration = one wavelength). The wave moves awa ...
