__**Explain that sound is produced by vibrating objects and that the frequency of the sound is the same as the frequency of the vibration of the source of the sound **__  due to being moved it will compose energy which is sound. It will cause a chain reaction which will cause the  near by air molecules to vibrate backwards and forwards.The frequency of these vibration will be the same as the object that of the (ಠ_ಠ)

object that had started the vibration. It is then converted to sound when it has reached the ear, The outcomes will be a compressed wave which travels through the air, sound requires a form to pass through eg: water and air. If a persons were to scream and the vibration was to reach 150 hertz, the air around it would vibrate the same .The speed of sound will be greater through a solid and slowest through gas.media type="youtube" key="MFLeGJclQiI" height="344" width="425" The animation above is indicating how sound is vibration and how it works behind the scenes
