The centimeter (abbreviation, cm) is a unit of displacement (distance or length) in the cgs (centimeter/gram/second) system of units.
One centimeter is the distance traveled by a ray of electromagnetic (EM) energy through a vacuum in 3.33564095 x 10-11 of a second. The centimeter and its kin are used to specify the wavelengths of EM fields, particularly at ultra-high and microwave radio frequencies. The so-called radio spectrum occupies an informally defined range of wavelengths from roughly 1 mm to several tens of kilometers. A 300-cm radio wave falls near the middle of the standard FM (frequency-modulation) broadcast band; a 1-cm radio wave corresponds to a frequency of approximately 30 gigahertz (GHz). The range of visible light wavelengths is from approximately 390 nm (violet) to 770 nm (red). The speed of EM-field propagation in a vacuum, to nine significant figures, is 2.99792458 x 1010 centimeters per second.
