The frequency range of ultraviolet waves is between 7.5 x 10^14 and 3 x 10^16 Hertz. For this range, the corresponding ultraviolet light wavelengths are 400 to 10 nanometers. Ultraviolet light waves are below the visible... More »

The frequency of a sound wave determines what people hear as pitch. A higher frequency has a higher pitch, and a lower frequency is heard as a lower pitch. The frequencies that humans can hear range from 20 to 20,000 Her... More »

Radio waves range from 300 gigahertz (GHz), or a wavelength of 1 millimeter, to 3 kilohertz (kHz), which corresponds to a wavelength of 100 kilometers. Radio waves are the lowest frequency within the electromagnetic spec... More »
