Vibrating produces sound.
sound energy is formed by a vibrating body. We can say that sound is produced only when a body is vibrating.
By vibrating
sound energy is formed by a vibrating body. We can say that sound is produced only when a body is vibrating.
It can be thermal energy if it is the atoms vibrating in a solid material. If the vibration is large enough it can cause acoustic energy, if the vibrating object is coupled to the atmosphere. If an object is vibrating in a magnetic field it can give off electromagnetic energy.
