Propagation of sound
Propagation of sound The sound is produced by the to and fro movement of an object which is also called as vibrations. The substances or matter through which sound is transmitted is called as medium. These medium can be solid, liquid or gas. The sound waves consist of the particles of the medium through which it travels. A sound is a form of energy which is transmitted in the form of the sound waves. Sound moves through the medium from the point of generation to the listener. When the object gets vibrates, then the air which is surrounding their also vibrates and sound waves are carried. When there is no medium, then vibration in an object will not travel through them. When an object get vibrates, the particles of the surrounding of the medium also vibrates. The particles do not travel all the way from the vibrating object to the ear. When the particle of the medium is contact with the vibrating object, the particle is first displaced from its equilibrium position. It then
