standing wave

noun

, Physics.

1. a wave in a medium in which each point on the axis of the wave has an associated constant amplitude ranging from zero at the nodes to a maximum at the antinodes.

standing wave

noun

1. 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 calledstationary wave Compare node antinode

standing wave

/ stăn′dĭng /

1. A wave that oscillates in place, without transmitting energy along its extent. Standing waves tend to have stable points, called nodes, where there is no oscillation. Examples of standing waves include the vibration of a violin string and electron orbitals in an atom.
2. Also called stationary wave
3. See also harmonic oscillator

Word History and Origins

Origin of standing wave¹

First recorded in 1905–10

Example Sentences

Each laser beam formed a standing wave, a periodic pattern of electric field intensity with a spatial period of 500 nanometers.

From Science Daily

Afterwards, it is possible, for example, to trap them in a standing wave of laser light.

From Science Daily

"The collision creates a standing wave that does not move. In the case of geometrically frustrated lattice materials, it's the electronic wave functions that destructively interfere."

From Science Daily

There is a standing wave of vulnerability and salvation that churns beneath the surface of Los Angeles, the great bipolar metropolis of the American West.

From Los Angeles Times

Especially for beginners, don’t expect your skill set from the ocean to translate to a standing wave, or vice versa.
