Assignment on difference between transverse wave and longitudinal wave

I thought I would give a more macro image of longitudinal vs. transverse waves. In longitudinal waves the particle motion is parallel to the direction, whereas transverse is perpendicular.
Transverse wave is like people doing the wave at a base ball game. You see people standing up, and that standing is perpendicular to the motion of the wave which appears to be going around the stadium seats. These are the easiest waves to see because the particles literally stand out. Waves of ocean water at the beach, the water particles move up and down, perpendicular to the wave that moves in toward the shore.
Longitudinal waves are harder to see, but quite easy to feel. Stand in line with a bunch of people then shove the person in front of you. What happens? They fall into and shove the person in front of the them who falls into an shoves the person in front of them, and this continues until you run out of people or the wave doesn’t have enough energy to continue. Longitudinal waves are usually collision of particles. A bumper to bumper car crash is another large example. Or a mosh pit at a rock concert. Shove and be shoved. It’s the collision that causes a collision that causes a collision, etc. Sound waves do this to the particles that they are traveling in. When someone talked to you, your ear drums don’t feel the particles that vibrates out of their mouth. The particles in their mouth create a wave of particle collisions like a massive multi vehicle car crash the spreads in many directions, until the air particles in your ear get bumped into, and they collide with your ear drum. So in air, water or any other medium, sound is a longitudinal wave.
Hope that helps.
