Echo vs. Reverberation
Sound is a mechanical wave that travels by a medium from a single location to other. This motion by a medium occurs as one particle of the medium interacts along with its neighbouring particle, transmitting the mechanical motion and corresponding energy to it. This transport of mechanical energy by a medium through particle interaction is what forms a sound wave a mechanical wave.
