The PHENOMENON which results when WAVES of the same or nearly the same FREQUENCY are superposed. It is charac­terized by a spatial or tempo­ral distribution of AMPLITUDE of some specified charac­teristic differing from that of the individual superpo­sed WAVES.
5982

The distance between corresponding points of two successive PERIODIC WAVES in the direction of propagation, for which the OSCILLATION has the same PHASE. Unit of measurement in METRES. Also written as one word.
5983

An instrument for measuring WAVES. One used for ocean waves usually measures HEIGHT and PERIOD; one used for ELECTROMAGNETIC or SOUND WAVES usually measu­res length. Also written as two words.
5984
wave of translation
A WAVE in which the individual particles of the medium are shifted in the direction of wave travel, as ocean waves in shoal waters. Distin­... more
A WAVE in which the individual particles of the medium are shifted in the direction of wave travel, as ocean waves in shoal waters. Distin­guished from an OSCILLATORY WAVE.
5985
wave period
The time, in SECONDS, required for a WAVE CREST to traverse a distance equal to one WAVE LENGTH.
5986
wave refraction
See REFRACTION OF WATER WAVES.
5987
wave spectrum
In ocean wave studies, a graph showing the distribution of WAVE HEIGHTS with respect to FRE­QUENCY in a wave record.
5988
wave train
A series of WAVES moving in the same direc­tion. See WAVE: SOLITARY.
5989

See TROUGH.
5990
wave velocity
The SPEED at which the individual wave form advances. A vector quantity that specifies the SPEED and direc­tion with which a SOUND WAVE tra... more
The SPEED at which the individual wave form advances. A vector quantity that specifies the SPEED and direc­tion with which a SOUND WAVE travels through a medium.
