A CDE Definition
The strength or volume of a signal, usually measured in decibels. See wavelength.
The distance between crests of a wave. The wavelength determines the nature of the various forms of radiant energy that comprise the electromagnetic spectrum. For electromagnetic waves, the wavelength in meters is computed by the speed of light divided by frequency (300,000,000/Hz). For sound waves, the wavelength is determined by 335/Hz. See optical bands.
