# longitudinal wave

## longitudinal wave

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

## longitu′dinal wave′

n.
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

(lŏn′jĭ-to͞od′n-əl)
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.

This equation describes longitudinal wave propagation only if the movement is provided along the x-axis.
In comparison with a non-clad buffer rod, which supports many high order propagation modes, the clad buffer rod supports on ly a few low order propagation modes including the most important one--the pure longitudinal wave.
In longitudinal wave motion the particles in the medium move parallel to the direction of propagation of the wave (like sound waves).
t) via the second quantization vector wave functions of one Sound Boson of the longitudinal wave.
In addition, due to the longer duration of the FEM signal, the expected reflections of the bulk longitudinal wave from the outer edge (radius of the block) and the bottom surface of the block are present in that signal.
where m is hybrid waves first (azimuthal) index, describes longitudinal wave constant component by the azimuthal perimeter coordinate [phi]; [N.
When a longitudinal wave travels through a solid the displacement particles vector has the same direction with the wave velocity vector.
This fact is useful because in the case of action of ultrasonic longitudinal wave in solid, the own frequency of ion-dipole can not be determined.
Initial weak waves arrived at 62 [micro]s from the excitation pulse, indicating the longitudinal wave velocity of 6.
The propagation of a longitudinal wave into a polymer is governed by the longitudinal modulus of the material, L = L[prime] + i L[double prime], resulting from the linear combination of the bulk (K) and the shear (G) moduli: L = K + 4G/3.
The longitudinal wave velocity was also measured and compared with AE generation behavior.
