In longitudinal waves, the oscillations are along the same direction as the direction of travel and energy transfer.

What direction does a longitudinal wave move?

Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport.

Do longitudinal waves have direction?

Longitudinal waves are waves in which the vibration of the medium is parallel to the direction the wave travels and displacement of the medium is in the same (or opposite) direction of the wave propagation.
