    (written as WAVE)


  • A periodic disturbance which is propagated through a medium or space. electromagnetic waves, for instance, are produced by the oscillation or acceleration of an electric charge, consist of sinusoidal electric and magnetic fields which are at right angles to each other and to the direction of motion, and propagate through a vacuum at the speed of light. There are other examples, including those caused by vibrations, such as acoustic waves. Characteristics which help describe waves include amplitude, frequency, waveform, wavelength, phase, and velocity. Waves can be classified in various manners. For instance, a wave may be longitudinal versus transverse, standing versus progressive, symmetrical versus non-symmetrical, and so on. As waves propagate, they may also undergo phenomena such as diffraction, refraction, reflection, and dispersion.

Origin & History of “wave”

English has two words wave, distinct in origin, which have grown to resemble each other over the centuries. The verb, ‘move to and fro’ (OE), goes back to a prehistoric Germanic base *wab-, which also produced English waver (14th c.) (borrowed from Old Norse vafra ‘move unsteadily’) and wobble (17th c.). The noun wave ‘movement of the sea’ (16th c.) seems to be an alteration (under the influence of the verb wave) of an earlier wawe ‘wave’. this in turn probably went back to Old English wǣg ‘motion, wave’, a derivative of the verb which produced modern English wag.
