Detailed explanation-1: -In a longitudinal wave, the direction of motion of the particle is parallel to the direction of propagation of wave. Sound wave is an example of this kind of wave, in which the direction of the particle is in same direction as the wave propagates.
Detailed explanation-2: -When the motion of the waves is parallel to the motion of the particles, then that type of wave is generally called as longitudinal waves. Q. In a longitudinal wave, the motion of a particle is perpendicular to the direction of propagation of wave.
Detailed explanation-3: -A longitudinal wave is one where the wave moves in the same direction as the material the wave moves through. So, for example, sound waves, which are longitudinal, push particles of air in the same direction as the wave moves overall.
