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:
“Most observers of the French Revolution, especially the clever and noble ones, have explained it as a life-threatening and contagious illness. They have remained standing with the symptoms and have interpreted these in manifold and contrary ways. Some have regarded it as a merely local ill. The most ingenious opponents have pressed for castration. They well noticed that this alleged illness is nothing other than the crisis of beginning puberty.”
—Novalis [Friedrich Von Hardenberg] (17721801)
“Wind goes from farm to farm in wave on wave,
But carries no cry of what is hoped to be.
There may be little or much beyond the grave,
But the strong are saying nothing until they see.”
—Robert Frost (18741963)
