|
5923 | water vapor | Water in the gaseous phase. |
|
5924 | waterway | A line of water (RIVER, CHANNEL, etc.) which can be utilized for communication or transport. |
|
5925 | watt | The unit of power in the SI system. |
|
5926 | wave | A disturbance which moves through or over the surface of the medium with SPEED dependent upon the properties of the medium. A ridge deformat... more |
|
5927 | wave: capillary | A WAVE whose VELOCITY of propagation is controlled primarily by the surface tension of the liquid in which the WAVE is travelling. Water wa... more |
|
5928 | wave: carrier | A RADIO WAVE used as a vehicle for conveying intelligence, generally by MODULATION. Also called carrier. |
|
5929 | wave: cellular | System of SURFACE WAVES in which the OSCILLATION of water is limited as by solid BOUNDARIES. The PERIOD is the same in adjacent cells. |
|
5930 | wave: compressional | A WAVE in an elastic medium which causes an element of the medium to change its volume without undergoing rotation. |
|
5931 | wave: continuous | A series of WAVES of like AMPLITUDE and FREQUENCY. See WAVE: MODULATED, PULSE. |
|
5932 | wave: cycloidal | A very steep, symmetrical WAVE whose CREST forms an angle of 120 DEGREES. The wave form is that of a cycloid. A TROCHOIDAL WAVE of maximum s... more |
|
5933 | wave(s): damped | WAVE(S) the AMPLITUDE of which becomes progressively smaller. |
|
5934 | wave: direct | A subdivision of the space wave component of the electromagnetic GROUND WAVE. This WAVE is propagated directly through space, i.e., it foll... more |
|
5935 | wave: edge | An ocean wave travelling parallel to a COAST, with CRESTS normal to the COASTLINE. Such a WAVE has a HEIGHT that diminishes rapidly seaward ... more |
|
5936 | wave: electromagnetic | WAVE(S) of associated electric and magnetic fields characterized by variations of the fields. The electric and magnetic fields are at right ... more |
|
5937 | wave: forced | A WAVE generated and maintained by a continuous force, in contrast to a FREE WAVE that continues to exist after the generating force has ce... more |
|
5938 | wave: free | A WAVE that continues to exist after the generating force has ceased to act, in contrast with a FORCED WAVE that is generated and maintained... more |
|
5939 | wave: gravity | A WAVE whose VELOCITY of propagation is controlled primarily by GRAVITY. Water waves of length greater than 2 INCHES are considered gravity ... more |
