Basic Electromagnetic Wave Properties - Electromagnetic radiation is characterized by a broad range of wavelengths and frequencies, each associated with a specific intensity (or amplitude) and quantity of energy.
(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.
