diagram of the basic components of a sound wave: frequency, wavelength and amplitude

The basic components of a sound wave are frequency, wavelength and amplitude. In this example of a sound wave, the period of one cycle of this wave is 0.5 seconds, and the frequency of this wave is 2 cycles per second or 2 Hertz (Hz). Image courtesy of Sounds in the Sea 2001, NOAA/OER.
