Sound is a form of energy produced and transmitted by vibrating matter. Sound waves caused. by such vibrations move through a medium (a solid, liquid, or gas) in all directions from their. source. However, the medium vibrates back and forth and transfers the energy; the medium is. not carried along with the sound wave. Sound waves can be described by the wavelength and frequency of the waves.
