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:
“Great Powers of falling wave and wind and windy fire,
With your harmonious choir
Encircle her I love and sing her into peace,
That my old care may cease....”
—William Butler Yeats (1865–1939)
“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 (1891–1980)
“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)
