Question

listen
given two strings next to each other on a musical instrument, which string would produce a sound of a lower pitch?
the string with the higher amount of tension
the string with the thinner diameter
the string of the shortest length
the string with the thicker diameter

Explanation:

Pitch of a vibrating string is related to its mass, tension, and length. Higher tension, thinner diameter, or shorter length all increase the string's vibration frequency, creating a higher pitch. A thicker string has more mass per unit length, which lowers its vibration frequency, producing a lower pitch.

Answer:

The string with the thicker diameter
