Traveling and Standing Waves
Since sine waves propagate without changing form in distributed linear systems, they are often used to analyze wave propagation. Sine waves traveling in two directions can be represented as
- and .
When two waves having the same amplitude and frequency, and traveling in opposite directions, superpose each other, then a standing wave pattern is created.

Famous quotes containing the words traveling, standing and/or waves:
“If the British prose style is Churchillian, America is the tobacco auctioneer, the barker; Runyon, Lardner, W.W., the traveling salesman who can sell the world the Brooklyn Bridge every day, can put anything over on you and convince you that tomatoes grow at the South Pole.”
—Ishmael Reed (b. 1938)
“Standing navies, as well as standing armies, serve to keep alive the spirit of war even in the meek heart of peace. In its very embers and smoulderings, they nourish that fatal fire, and half-pay officers, as the priests of Mars, yet guard the temple, though no god be there.”
—Herman Melville (1819–1891)
“What is Americanism? Every one has a different answer. Some people say it is never to submit to the dictation of a King. Others say Americanism is the pride of liberty and the defence of an insult to the flag with their gore. When some half-developed person tramples on that flag, we should be ready to pour out the blood of the nation, they say. But do we not sit in silence when that flag waves over living conditions which should be an insult to all patriotism?”
—Anna Howard Shaw (1847–1919)
