Sound waves are like invisible ripples you can feel when something moves through air, just like when you shake a blanket and see it ripple.
How Sound Waves Move
What Sound Waves Look Like
If you could see sound, it would look like waves on water, high and low parts moving through the air. You can think of it like when you drop a stone in a pond: ripples spread out from where the stone hit the water. Sound waves do something similar, but with air instead of water.
When you listen to music or talk, these invisible waves are traveling all around you, just waiting for your ears to catch them and turn them into sound!
Examples
- A teacher draws waves on the board to show how sound travels.
- Someone uses a phone app that turns music into colorful patterns.
