| 释义 | longitudinal wave noun[ C ] physics specializeduk /lɒn.dʒɪˌtjuː.dɪ.nəl ˈweɪv/ us /lɑːn.dʒəˌtuː.dɪ.nəl ˈweɪv/ a wave moving in the same direction of travel as the vibrations (= fast movements backwards and forwards) of the particles of the substance through which it is travelling纵波（物理学中振动方向与传播方向在同一方向上的波） Compare transverse wave Physics: energy, force & power animal magnetism anti-gravity atmospheric pressure attract attraction ballistic entropic entropically equilibrant erg excited geothermal inertia preatomic propulsive radiant energy self-propulsion sine curve the sound barrier thermodynamics longitudinal wave | American Dictionarylongitudinal wave noun[ C ] us/ˈlɑn·dʒəˈtu·dən·əl ˈweɪv/ physics a wave in which the substance the wave travels through moves in the same direction of the wave itself. Sound waves are longitudinal waves. Examples of longitudinal wavelongitudinal wave Tesla researched ways to transmit energy wirelessly over long distances, first by transverse waves, and then, possibly, by longitudinal waves.

The length-to-width ratio 1 is assumed t o be far from integral multiples of so that the longitudinalwave is not resonantly excited. For such conditions, the amplitude of the longitudinalwave is of higher order than that of the resonant cross-wave. The second inequality refers to the stability of the stationary longitudinalwave subject to transverse perturbations. Production of high-quality electron beams in numerical experiments of laser wakefield acceleration with longitudinalwave breaking. On the stable branch, starting from the turning point, the amplitude of the longitudinalwave decreases while the amplitude of the transverse wave increases and dominates the three-dimensional wave motion. The rarefaction is the farthest distance apart in the longitudinalwave and the compression is the closest distance together. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. One compression and one rarefaction make up one longitudinalwave.

Lower frequencies and those at or below longwave bands travel most efficiently as a longitudinalwave and create stationary waves.

The opposite of a transverse wave is a longitudinalwave, where the vibrations are in the same direction as the wave travel.

With respect to the direction of the oscillation relative to the propagation direction, we can distinguish between longitudinalwave and transverse waves.
