Question

If you tighten a guitar string, _____.

the string will vibrate slower
the string will vibrate faster
the pitch of the string will drop
the frequency of its sound will decrease

Answer 1

The correct answer is: the string will vibrate faster.

As you tighten the guitar string, the tension in the string increases, which causes the speed of sound waves traveling through the string to increase. This, in turn, leads to an increase in frequency and a higher pitch. So, when you tighten a guitar string, it vibrates faster.
