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:

    Children are as destined biologically to break away as we are, emotionally, to hold on and protect. But thinking independently comes of acting independently. It begins with a two-year-old doggedly pulling on flannel pajamas during a July heat wave and with parents accepting that the impulse is a good one. When we let go of these small tasks without anger or sorrow but with pleasure and pride we give each act of independence our blessing.
    Cathy Rindner Tempelsman (20th century)

    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)

    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)
