A guitar string with mass density 000021 kgm is l 095 m, Ask an Expert

Academics

A guitar string with mass density ? = 0.00021 kg/m is L = 0.95 m long on the guitar. The string is tuned by adjusting the tension to T = 82.6 N.

1) With what speed do waves on the string travel?

2) What is the fundamental frequency for this string?

3) Someone places a finger a distance 0.15 m from the top end of the guitar. What is the fundamental frequency in this case?
