| 14. | physics antinode longitudinal wave node standing wave See also transverse wave an oscillation propagated through a medium or space such that energy is periodically interchanged between two kinds of disturbance. For example, an oscillating electric field generates a magnetic oscillation and vice versa, hence an electromagnetic wave is produced. Similarly a wave on a liquid comprises vertical and horizontal displacements |

wave (wāv)
n.
A disturbance traveling through a medium by which energy is transferred from one particle of the medium to another without causing any permanent displacement of the medium itself.
A graphic representation of the variation of such a disturbance with time.
A single cycle that is representative of such a disturbance.
wave (wāv) Pronunciation Key
(click for larger image in new window) A disturbance, oscillation, or vibration, either of a medium and moving through that medium (such as water and sound waves), or of some quantity with different values at different points in space, moving through space (such as electromagnetic waves or a quantum mechanical wave described by the wave function). See also longitudinal wave, transverse wave, wave function. See Note at refraction. |
In physics, any regularly recurring event, such as surf coming in toward a beach, that can be thought of as a disturbance moving through a medium. Waves are characterized by wavelength, frequency, and the speed at which they move. Waves are found in many forms.
Note: The motion of a wave and the motion of the medium on which the wave moves are not the same: ocean waves, for example, move toward the beach, but the water itself merely moves up and down. Sound waves are spread by alternating compression and expansion of air.
