(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] length of wire

1. The problem statement, all variables and given/known data

A wire of mass 1.1 g is under a tension of 100 N. If its third overtone is at a frequency of 750 Hz, calculate the length of the wire.

3. The attempt at a solution

v = sqrt(FL/m) = 301.5*sqrt(L)

f_{n}= n*v/(2*L) --> L = n*v/(2*f_{n}) --> L = 0.36 m

The book says 0.65 m. Am I wrong?
