The term used in seismology is the S-wave.
The primary factor that determines the velocity of a wave is the medium through which the wave is traveling.
Primary Wave (P wave)
A primary wave is a strong vibration or wave that hits earths surface (P) and a secondary wave (S) is a wave that hits soon after but not nearly as big.
The primary body wave that is a longitudinal wave is the P-wave (primary wave). It is the fastest seismic wave and travels through the Earth's interior by compressing and expanding the rock in the direction of the wave's propagation.
The primary wave (P-wave) vibrates in the same direction as the wave propagation. This means that the particles in the material move back and forth parallel to the direction of wave travel as the P-wave passes through.
The apostrophe in "wave's" indicates possession, such as "the wave's crest." It can also be used in contractions, like "wave's been" for "wave has been."
