Sound waves can go through air, which is how we normally experience it. So when you see a snake-like illustration of a sound wave, it’s referring to the measure of pressure, not the literal path of movement of the particles: 5 So instead of a curvy snake wave, sound is a pressure wave, which causes each piece of the air to be at either higher-than-normal pressure or lower-than-normal pressure. By looking at the red dots, you can see that even though the wave moves in one direction, each individual particle only moves back and forth, mimicking the vibration of the gray bar.

The bar might be your vocal chords, a guitar string, or a waterfall continually pounding down into the river below. In this animation, the sound wave is being generated by that vibrating grey bar on the left. That’s what sound looks like-except picture an expanding ripple of spheres doing that. Sound starts with a vibration of some kind creating a longitudinal wave through matter. Like an earthworm, sound moves by compressing and decompressing. A wave like that is called a transverse wave, where each individual particle moves up and down to create a snake situation.Ī sound wave is more like an earthworm situation: 2 The way a vibration “goes through” matter is in the form of a sound wave. When you think of sound waves, you probably think of something like this: 1īut that’s not how sound waves work. But in pure physics terms, sound is just a vibration going through matter. We think of sound as something we hear-something that makes noise. So for “Tuesday’s” “mini” post, I decided to do something about that. I’ve always been a little confused about sound. This post is part of Mini Week, where I’m posting a new mini post but not actually mini as it turns out every weekday this week.
