longitudinal wave

Also found in: Encyclopedia, Wikipedia.

longitudinal wave

(General Physics) a wave that is propagated in the same direction as the displacement of the transmitting medium. Compare transverse wave

longitu′dinal wave′

a wave in which the direction of displacement is the same as the direction of propagation, as a sound wave.

lon·gi·tu·di·nal wave

A wave in which the particles of the medium through which the wave moves vibrate in the same direction as the wave travels. Sound waves are a type of longitudinal waves. See more at wave. Compare transverse wave.

Particles propagate in the spacetime continuum as longitudinal wave displacements.
In this case, the TT samples had a thickness along the axis of compression and the ultrasonic measurements provided the longitudinal wave modulus along this axis, and the TA samples had a thickness along the direction perpendicular to the axis of compression and so the ultrasonic tests provided the longitudinal wave modulus along the transverse direction.
The time distribution of the loading point force, applied at point A, is prescribed by the rectangular pulse, whose duration corresponds to time when the primary longitudinal wave reaches half the length of the specimen.
The values of longitudinal wave and shear wave velocities of fresh and weathered oil shale and rock samples, in both horizontal bedding orientation and vertical bedding direction, are given in Table 1.
The wave is composed of 1) a torsional wave and 2) a longitudinal wave.
