Explain with the help of diagram how sound propagate through air.​

see below, but I can't add a diagram

Explanation:

When the source vibrates, it causes particles near it to vibrate back and forth vigorously. As these particles vibrate, they collide with the neighbouring particles , passing on the energy and making them vibrate vigorously. this forms a series of compressions and rarefactions . this process continues as a longitudinal wave until the vibrations reach our ear

hope this helps,

please mark it brainliest

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.
