A tuner hears beats slow down as two strings are tuned. What is happening to their pitches?
AThey approach unison
BThey drift apart
CThe amplitudes grow
DBoth stop vibrating
Answer & Solution
Correct answer: A. They approach unison
As the frequency difference shrinks, the beat rate falls and vanishes at unison.
