Explain the physics of the generation of sound for a musical instrument of your choice.
Probably the simplest choice would be a stringed instrument.Originally Posted by Celia
Briefly: The sound is produced by the vibration of a string which vibrates (more or less) as a standing wave. This vibration disturbs the air molecules near the string, which creates a sound wave.
The string itself is too small to produce much sound so it has to be connectedOriginally Posted by topsquark
to a large object (via a/the bridge?) which moved more air when it vibrates
and so more sound, which in its turn may stimulate a cavity with lots of
resonances to produce even more sound.
