Detailed explanation-1: -If you drop a meter stick or pencil on the floor, it will begin to vibrate. If you pluck a guitar string, it will begin to vibrate. If you blow over the top of a pop bottle, the air inside will vibrate. When each of these objects vibrates, they tend to vibrate at a particular frequency or a set of frequencies.
Detailed explanation-2: -Sound energy is the result when a force, either sound or pressure, makes an object or substance vibrate. That energy moves through the substance in waves. Those sound waves are called kinetic mechanical energy.
Detailed explanation-3: -When an object vibrates, it forces the neighbouring particles of the medium to vibrate. These vibrating particles then force the particles adjacent to them to vibrate. In this way vibrations produced by an object are transferred till it reaches the ear.
Detailed explanation-4: -Explanation: Whenever an object is vibrating, we say that it has energy in its kinetic energy form. This can be explained that whenever the object starts to vibrate it is utilizing its energy by converting it into the kinetic form.
