a wave propagated at the speed of light by the periodic variations of electric and magnetic fields. electromagnetic wave. A wave of energy consisting of oscillating electric and magnetic fields. Radio waves, light waves, and x-rays are electromagnetic waves.
(This is because the product of frequency and wavelength is always the speed of the wave. For light, that speed is constant.) Mathematically: frequency = speed of light/wavelength. An electromagnetic wave is a synonym for light, because it consists of waves of electric and magnetic fields. Wavelength is the distance from one peak of an electromagnetic wave to the next.
