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 wave and/or standing:
“As the bird trims her to the gale,
I trim myself to the storm of time,
I man the rudder, reef the sail,
Obey the voice at eve obeyed in prime:
Lowly faithful, banish fear,
Right onward drive unharmed;
The port, well worth the cruise, is near,
And every wave is charmed.”
—Ralph Waldo Emerson (18031882)
“The despotism of custom is everywhere the standing hindrance to human advancement.”
—John Stuart Mill (18061873)
