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:
“Lawyers are necessary in a community. Some of you ... take a different view; but as I am a member of that legal profession, or was at one time, and have only lost standing in it to become a politician, I still retain the pride of the profession. And I still insist that it is the law and the lawyer that make popular government under a written constitution and written statutes possible.”
—William Howard Taft (18571930)
“The city is loveliest when the sweet death racket begins. Her own life lived in defiance of nature, her electricity, her frigidaires, her soundproof walls, the glint of lacquered nails, the plumes that wave across the corrugated sky. Here in the coffin depths grow the everlasting flowers sent by telegraph.”
—Henry Miller (18911980)
