As much as people listen to music for the beauty and sound, no one really sees the physics behind music and sound waves. Sound is an example of a mechanical wave. A mechanical wave is a wav that propagates as an oscillation of matter, and transfers energy through a medium. mechanical waves transfer energy only. Sound is a wave created by vibration moving from one medium to another. These vibrations are the reason why we can hear sounds such as music. With music speakers, am object vibrates in the air, and these air particles move around them. This carries the pulse of vibration as a traveling disturbance. This shows how the basis for an understanding of sound and music is the physics of waves.
