Physics 2021 JAMB Past Questions - Question 29:  The note from a plicked guitar string will have a low pitch if the string is

Correct Answer

B

Explanation

The pitch of a plucked guitar string is primarily determined by its tension, length, and mass per unit length. In general, if a guitar string is thicker (has more mass per unit length), it will vibrate more slowly and produce a lower pitch when plucked. Additionally, lower tension in the string and a longer effective vibrating length (for example, by pressing the string against a fret farther from the nut) can also contribute to a lower pitch.

So, to summarize, a guitar string will have a low pitch if it is thick, has lower tension, and is played with a longer effective vibrating length.
