Anatomy of a Longitudinal Wave

Longitudinal waves are waves in which the displacement of the medium is in the same direction as, the direction of propagation or movement of the wave. In other words, the displacement of the medium is parallel to the propagation of the wave

Longitudinal waves are also called compressional or compression waves, because they produce compression and rarefaction when traveling.
I also cover compressions and rarefactions.
