Longitudinal Waves
In a longitudinal wave, the particles of the medium move parallel to the wave's direction of travel. Let's go back to our line of people to see what this would look like.
In this scenario, instead of the person on the left jumping up and down, they bump into the person next to them. Now, this next person being knocked off balance will bump into the person beside them, and so on down the line. As each person regains their balance, they return back to the place where they were standing before being so rudely disturbed. As we can see, the wave traveled from left to right again, but this time the motion of the people was also left and right. To help us remember this relationship, we can think about how the motion of the particles is along the longitudinal wave.
While transverse waves have crests and troughs, longitudinal waves have compressions and rarefactions. A compression is where the density of the wave medium is highest. In our line of people, this was where folks were actually bumping into each other. A rarefaction is where the density of the wave medium is lowest. In our line, this occurred just after the compression, where the people were spread out, trying to regain their balance. Just like the wavelength of a transverse wave is the distance from crest to crest or trough to trough, the wavelength of a longitudinal wave is the distance between compressions or between rarefactions

Examples of longitudinal waves include sound waves, earthquakes and ocean currents; these waves can move through air, solids or liquids.

Longitudinal waves are always characterized by particle motion being parallel to wave motion.
Hope it helps ❤️❤️❤️
