Resonance and SoundPhysics and MusicSince sound is the medium of music, most of the physics of music is the physics of sound.Its important to reckon that sound waves are compression waves. You can imitate a compression wave by stretching out a slinky (you do have a slinky, dont you?) and flicking your finger against a coil at the end. Sound waves are not like the waves on the ocean or the waves you get by waving a stretched-out rope.Take a tuning furcation (you do have a tuning fork, dont you?) and whack it on your knee. What do you hear? Unless you hold the tuning fork right next to your ear, you wont hear much of anything. This is because a small tuning fork cant push very much air around. Now take the akin tuning fork, whack it on your knee again, and touch the non-forked end to a tabletop or other handy wooden surface. The sound should be a lap louder. This is because the vibrating tuning fork causes the tabletop to vibrate. The tabletop can push much more air around than th e fork alone. If you touched the end of the tuning fork to a dig box or, say, the body of a guitar, the sound would be even louder. This is because the vibrations get transferred to the air inside the box, which vibrates as well. If the dimensions of the inside of the box are a manifold of the wavelength of the sound, some of the sound waves will reinforce each other for even more volume. If a vibration or sound wave can actuate another object into vibrating, the second object is sai...
