surface wave
surface waven. A seismic wave that travels across the surface of the earth rather than through it. Surface waves usually travel more slowly and have larger amplitudes and longer wavelengths than body waves.surface wave An earthquake wave in which rock particles vibrate at right angles to the direction of wave travel. Surface waves travel only on the Earth's surface, and not through it. Also called L wave. See Note at earthquake.surface wave
surface wave[′sər·fəs ‚wāv] (communications) ground wave (electromagnetism) A wave that can travel along an interface between two different mediums without radiation; the interface must be essentially straight in the direction of propagation; the commonest interface used is that between air and the surface of a circular wire. (fluid mechanics) A wave that distorts the free surface that separates two fluid phases, usually a liquid and a gas. (mechanics) Rayleigh wave (oceanography) A progressive gravity wave in which the disturbance is of greatest amplitude at the air-water interface. surface waveThe part of a radio transmission that follows the earth's surface. The same as a ground wave. See space wave.AcronymsSeesubwayThesaurusSeeground wave |
