A waveform in which the vibrations of the medium it is propagated through are in the same direction as the wave's travel.
A waveform in which the vibrations of the medium it is propagated through are in the same direction as the wave's travel. Sound waves are examples of longitudinal waves. As a sound travels through air, particles in the air move back and forth in the same direction as the wave travels. Longitudinal waves may also be referred to as compression waves.
