Longitudinal (compression) waves made by vibrating matter Sound Waves 15.2 Sound Waves A sound wave is a wave of alternating high-pressure and low-pressure regions of air. Sound waves need a medium to travel Sound travels faster through denser mediums Does sound travel faster through water or a...
Longitudinal waves are the mechanical waves in which the vibration of the particles takes place in the same direction as that of the wave. Sound waves, seismic waves are the examples of longitudinal waves.
In water and other fluids, waves are more complicated. Water particles on the surface will move up and down as a wave passes – transverse motion – but they will also experience compression at the top of the wave and rarefaction at the bottom – longitudinal motion. In fact, if you ...
These waves are called longitudinal waves. These waves are formed by the compression of particles. An example of a longitudinal wave is sound. For example, when a person talks, their vocal cords vibrate and push on air. These air particles then push on other air particles, that push on ...
the longitudinal normal cleavage cracking along the compression axis. As shown inFigure 9.58of the macro-fracture configuration of the DP3 specimen, the longitudinal normal cracking dominates the fracture (longer than the half length of the fracture surface). However, for the FL3 specimen, the ...

The paper contains a short survey of the papers on the static and dynamic longitudinal compression of a thin rod initiated by Morozov and and carried out in 2009鈥 2016 with his direct participation. We consider linear and nonlinear problems related to the propagation of longitudinal waves in a...
