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:
“Progress celebrates Pyrrhic victories over nature. Progress makes purses out of human skin. When people were traveling in mail coaches, the world got ahead better than it does now that salesmen fly through the air. What good is speed if the brain has oozed out on the way? How will the heirs of this age be taught the most basic motions that are necessary to activate the most complicated machines? Nature can rely on progress; it will avenge it for the outrage it has perpetrated on it.”
—Karl Kraus (1874–1936)
“The bourgeoisie and the petty bourgeoisie have armed themselves against the rising proletariat with, among other things, “culture.” It’s an old ploy of the bourgeoisie. They keep a standing “art” to defend their collapsing culture.”
—George Grosz (1893–1959)
“O beautiful for spacious skies,
For amber waves of grain,
For purple mountain majesties
Above the fruited plain!”
—Katharine Lee Bates (1859–1929)
