Sound waves are longitudinal or Transverse?

Sound waves are longitudinal waves in air (and any other fluid medium) because particles of the medium of Sound waves vibrate parallel to the direction of propagation of waves.

Longitudinal Sound Waves –

A longitudinal wave is a wave in which the motion of the medium’s particles is parallel to the direction of the energy transport. If you push a slinky back and forth, the coils move in a parallel fashion (back and forth). Similarly, when a tuning fork is struck, the direction of the sound wave is parallel to the motion of the air particles.
