How do air molecules enable sound to travel from a radio’s speaker to your ears? They push together and apart allowing the sound wave to travel as it vibrates from the radio speaker to your ear. Describe a compression and a rarefaction of a sound wave traveling through the air.
How does vibration make sound?
Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.
