when you pluck a guitar string, it vibrates. but so does the body of the guitar! this transfer of vibration…

Answer:

D. resonance

Brief Explanations:

When a guitar string is plucked, it vibrates at its natural frequencies. This vibration is transferred through the bridge to the body of the guitar. The guitar body also has its own natural frequencies of vibration. When the frequency of the vibrating string matches one of the natural frequencies of the guitar body, the body vibrates with a large amplitude. This phenomenon, where an object is forced to vibrate at its natural frequency by an external source (the vibrating string), resulting in a significant increase in amplitude, is called resonance. Resonance is crucial for amplifying the sound produced by the guitar strings.
