standing wave

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.

standing wave

(General Physics) physics the periodic disturbance in a medium resulting from the combination of two waves of equal frequency and intensity travelling in opposite directions. There are generally two kinds of displacement, and the maximum value of the amplitude of one of these occurs at the same points as the minimum value of the amplitude of the other. Thus in the case of electromagnetic radiation the amplitude of the oscillations of the electric field has its greatest value at the points at which the magnetic oscillation is zero, and vice versa. Also called: stationary wave Compare node, antinode

stand′ing wave′

a wave in which each point on the wave has a constant amplitude, ranging from zero at the nodes to a maximum, equal to the amplitude of the wave, at the antinodes.

stand·ing wave

A wave that does not appear to move. Standing waves occur when two similar waves travel in opposite directions between two fixed points, called nodes, at which there is no movement. Standing waves can be transverse waves, like ocean waves, or longitudinal waves, like sound waves. Also called stationary wave.
