How do the particles of the medium move in a longitudinal waves?

Answer 1

In a longitudinal wave, the particles of the medium move parallel to the direction of the wave. This means that the particles oscillate back and forth in the same direction that the wave is traveling. As the wave passes through the medium, each individual particle is pushed and pulled in the same direction as the wave, causing a back-and-forth motion. This movement of particles helps to transfer the energy of the wave through the medium.
