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:
“Now I stand as one upon a rock,
Environed with a wilderness of sea,
Who marks the waxing tide grow wave by wave,
Expecting ever when some envious surge
Will in his brinish bowels swallow him.”
—William Shakespeare (1564–1616)
“As the bird trims her to the gale,
I trim myself to the storm of time,
I man the rudder, reef the sail,
Obey the voice at eve obeyed in prime:
“Lowly faithful, banish fear,
Right onward drive unharmed;
The port, well worth the cruise, is near,
And every wave is charmed.””
—Ralph Waldo Emerson (1803–1882)
“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.”
—T.S. (Thomas Stearns)
