The strings of a guitar vibrate at different frequencies. They have different thicknesses because
A) a thinner string has more tension than a thicker string and vibrates at a higher frequency.
B) a thicker string has more tension than a thinner string and vibrates at a higher frequency.
C) a thicker, more massive string vibrates at a lower frequency than a thinner string of the same length and tension.
D) a thinner, less massive string vibrates less frequently than a thicker string of the same length and tension.

Question

Quizplus · Accepted Answer

A thicker, more massive string vibrates at a lower frequency than a thinner string when both have the same length and tension, due to the increased mass per unit length of the thicker string. This principle is why guitars and other stringed instruments use strings of varying thicknesses to produce different notes.
