## Homework Statement

A guitar string is 90.0 cm long and has a mass of 3.17 g. From the bridge to the support post is 60.0 cm and the string is under a tension of 506 N. What are the frequencies of the fundamental and first two overtones? (f

_{1},f

_{2},f

_{3})

## Homework Equations

v=sqrt(F

_{T}/m/

*l*)

v=[tex]\lambda*f[/tex]

## The Attempt at a Solution

I checked in my text and found that for f

_{1},

*l*=1/2[tex]\lambda[/tex]

_{1}; for f

_{2},

*l*=[tex]\lambda[/tex]

_{2}; and for f

_{3},

*l*=3/2[tex]\lambda[/tex]

_{3}. I tried using 60.0 cm (and converted to meters) and 90.0 cm (converted to meters) and 30.0 cm (converted to meters) for

*l*, but nothing worked. I also converted 3.17 g into kilograms so that's not an issue. I'm not sure what to do now..
