Answer / gautam

Vibration is to and fro motion of particles from its mean position.
Hence if one particle is executing this motion then it will be transmitted
to the adjuscent particle,and the whole body will vibrate.
In that condition if any near by material ,which is elastic comes into
cotact with the vibrating body,then som kinetic energy will be
transmitted and another body will also start vibrating.
But if the body is not elastic then it may collapse or absorbe whole
kinetic energy of the vibrating body, bringing it to rest.
