“The disturbance created by a source of sound in the medium travels through the medium and not the particles of the medium.” Justify this statement.
The correct option is A the medium A particle of the medium in contact with the vibrating object is displaced from its equilibrium position. This particle then exerts a force on the particle adjacent to it and displaces the particle from its position of the rest. The first particle then again comes back to its position of equilibrium. So there is no permanent displacement of the particles. Hence the disturbance created by source travels through the medium and not the particles of the medium.
