THE ENERGY FROM ELECTRIC CHARGES IN MOTION IS DISSIPATED THROUGH THE ELECTRIC AND MAGNETIC FIELDS IN THE FORM OF WAVES. THESE WAVES REPRESENT THE MANY FORMS OF ELECTROMAGNETIC RADIATION: RADIO WAVES, MICROWAVES, INFRARED WAVES, VISIBLE LIGHT WAVES, ULTRAVIOLET RAYS, X-RAYS AND GAMMA RAYS.

Disturbances in the electric and magnetic fields race outward together as a coupled pair of waves at the speed of light: about 300 000 000 m/s. The energy from these waves increases with the frequency of the waves, with radio waves on the low end to gamma rays on the high end. In the past century, humans have devised many ingenious ways to make use of the energies of each type.
