standing wavestanding wave
an oscillatory motion with a definite wavelength, frequency, and amplitude and having stationary, regularly spaced points where there is no motion: all the movement of the wave is contained between these nodes, thus providing for no net transport of energy
A wave that oscillates in place and creates stable nodes of maximum and zero oscillation, produced whenever a wave is confined within boundaries, as in the vibrating string of a musical instrument. Also called stationary wave.
(plural standing waves)
- A wave form which occurs in a limited, fixed medium in such a way that the reflected wave coincides with the produced wave. A common example is the vibration of the strings on a musical stringed instrument.
