## Homework Statement

A 60 cm guitar string under a tension of 50.000N has a mass per unit length of 0.100 g/cm. What is the highest resonant frequency that can be heard by a person capable of hearing frequencies up to 20000 HZ?

## Homework Equations

f= n/2L * sqrt(F/ greek letter mu)

wavelength = velocity/ frequency. ([tex]\lambda[/tex]= v*f)

## The Attempt at a Solution

I have mu = .100g/cm = .01 kg/m

f= 20000 HZ (not sure if this applies)

L= 60 cm = .6m

When I use,

f= n/2L * sqrt(F/ greek letter mu), I don't have n and I don't know how to find it.

Soneone please help. It's part of my final and worth 15 points. That's a letter grade. The answer is 19 khz or .019 hz.
