Detailed explanation-1: -Longitudinal waves are characterized by the motion of particles of the medium along the direction of wave propagation. Particles make to and fro motion in the direction of wave propagation and transfer energy to the neighbouring particles.

Detailed explanation-2: -In a longitudinal wave the particles are displaced parallel to the direction the wave travels. An example of longitudinal waves is compressions moving along a slinky.

Detailed explanation-3: -Since air molecules (the particles of the medium) are moving in a direction that is parallel to the direction that the wave moves, the sound wave is referred to as a longitudinal wave.

Detailed explanation-4: -A periodic wave repeats the same oscillation for several cycles, such as in the case of the wave pool, and is associated with simple harmonic motion. Each particle in the medium experiences simple harmonic motion in periodic waves by moving back and forth periodically through the same positions.

Detailed explanation-5: -Longitudinal waves are waves in which the individual particles of the medium move in a direction parallel to the direction of propagation of the disturbance. The particles do not move from one place to another but they simply oscillate back and forth about their position of rest.
