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:
“Suddenly he found he had pressed the spring of the grenade. He struggled to pull it out of his pocket. It stuck in the narrow pocket. His arm and his cold fingers that clutched the grenade seemed paralyzed. Then a warm joy went through him. He had thrown it.
Anderson was standing up, swaying backwards and forwards. The explosion made the woods quake.”
—John Dos Passos (1896–1970)
“And his wish is intimacy,
Intimater intimacy,
And a stricter privacy;
The impossible shall yet be done,
And, being two, shall still be one.
As the wave breaks to foam on shelves,
Then runs into a wave again,
So lovers melt their sundered selves,
Yet melted would be twain.”
—Ralph Waldo Emerson (1803–1882)
