Sound Waves

In physics, sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a medium such as air or water. Sound is a mechanical wave phenomenon and is normally associated with our sense of hearing. Sound is a property of vibrating objects.

• Sound is produced by vibrating sources in a material medium. Medium can be any gas, liquid or solid.
• The vibrating sources set the particles of a medium in vibration in such a way that sound travels outwards in the form of longitudinal waves.
• Some of the energy of the vibrations are transmitted over a distance.
