The Mystery of Standing Waves: How Do Guitar Strings Produce Sound?

Click For Summary
SUMMARY

A standing wave on a guitar string produces sound by imparting vibrations to surrounding air molecules, despite the wave itself transferring no energy along the string. The energy required for sound production originates from the initial plucking or strumming of the string, which creates the standing wave. This phenomenon illustrates the relationship between standing waves and sound energy generation in musical instruments.

PREREQUISITES

if a standing wave is a wave which transfers no energy, how is it that a guitar string produces a sound? because it produces it via a standing wave, and the sound is sound energy, so where does the energy come from?
 
Physics news on Phys.org
A standing wave on a string carries no energy from one end of the string to the other.

It can, and does impart vibration on the air molecules around it, resulting in sound waves.

ah yes. sorry, that was kind of obvious!
