What does it form when one part of a vibration causes air particles to spread out?
When one part of a vibration causes air particles to spread out, it forms a rarefaction in the air. This is a region where the air particles are more spread out compared to the surrounding areas of compression. Together, these rarefactions and compressions create sound waves that propagate through the air.
