✔️ Topic Name: Propagation of Sound

"Sound is produced by vibrating objects. The matter or substance through which sound is transmitted is called a medium.It can be
solid, liquid or gas. Sound moves through a medium from the point of generation to the listener. When an object vibrates, it sets the
particles of the medium around it vibrating.The particles do not travel all the way from the vibrating object to the ear. A particle of
the medium in contact with the vibrating object is first displaced from its equilibrium position. It then exerts a force on the adjacent
particle. As a result of which the adjacent particle gets displaced from its position of rest. After displacing the adjacent particle the
first particle comes back to its original position. This process continues in the medium till the sound reaches your ear."
