# What Are Longitudinal Waves?

Longitudinal wave is a kind of wave that pulsates in the direction of propagation. This term can also be used to refer to a wave that moves to and fro on an axis that is the same as the axis along which the wave propagates.

longitudinal wave
NOUN [PHYSICS.]
1.
a wave in which the direction of displacement is the same as the direction of propagation, as a sound wave.

Longitudinal waves are disturbances in which particles of a medium are displaced in a direction parallel to energy transport. As one individual particle is disturbed, it transmits the disturbance to the next interconnected particle. With another type of wave, known as a transverse wave, particles of the medium are displaced in a direction perpendicular to the direction of energy transport.
A longitudinal wave is a wave that has a periodic disturbance that is advancing in the same direction as itself. The particles that participate in the wave motion behave in the same way and vibrate along the axis of propagation. Primary seismic waves are a practical application of longitudinal waves.
Longitudinal waves cause particles to oscillate, or move back and forth around a center, along a line in the direction the waves are moving. Sound waves are considered longitudinal waves.
