Wave
In physics a wave is a disturbance or oscillation that travels through spacetime, accompanied by a transfer of energy. Wave motion transfers energy from one point to another, often with no permanent displacement of the particles of the medium—that is, with little or no associated mass transport. They consist, instead, of oscillations or vibrations around almost fixed locations. Waves are described by a wave equation which sets out how the disturbance proceeds over time. The mathematical form of this equation varies depending on the type of wave.

Famous quotes containing the word wave:
“I sometimes compare press officers to riflemen on the Somme—mowing down wave upon wave of distortion, taking out rank upon rank of supposition, deduction and gossip.”
—Bernard Ingham (b. 1932)
“Well, from what you tell me I should say that it was not only a landslide but a tidal wave and holocaust all rolled into one general cataclysm.”
—William Howard Taft (1857–1930)
“Through the dark cold and the empty desolation,
The wave cry, the wind cry, the vast waters
Of the petrel and the porpoise. In my end is my beginning.”
