(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I was told that a string on a guitar vibrates at a frequency of 110 Hz. The length of the string is .648 m and the tension is 100 N. I was told to find the mass per unit length, μ, of the string. Although I got the correct answer, I was wondering why my initial attempt was incorrect (shown below).

2. Relevant equations

[itex]f_{n}[/itex] = [itex]\frac{n}{2L}v[/itex]

[itex]v[/itex] = [itex]\sqrt{\frac{T}{μ}}[/itex]

3. The attempt at a solution

(Sorry for the formatting, I don't type in latex really quickly).

In this case, if it's a guitar, why is the velocity of the wave not equivalent to 345 m/s (343.2 m/s)? Why is it so much lower (142.56 m/s)?

Thank you.
