In physics, a standing wave – also known as a stationary wave – is a wave that remains in a constant position.
This phenomenon can occur because the medium is moving in the opposite direction to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions. In the second case, for waves of equal amplitude traveling in opposing directions, there is on average no net propagation of energy.
In a resonator, standing waves occur during the phenomenon known as resonance.

Famous quotes containing the words standing and/or wave:
“There will always be in society certain persons who are mercuries of its approbation, and whose glance will at any time determine for the curious their standing in the world. These are the chamberlains of the lesser gods. Accept their coldness as an omen of grace with the loftier deities, and allow them all their privilege.”
—Ralph Waldo Emerson (1803–1882)
“I hear
the tide turning. Last
eager wave over-
taken and pulled back
by first wave of the ebb.”
—Denise Levertov (b. 1923)
