# Homework Help: How to calculate 1st Overtone Frquency

How to I calculate the overtone frequency and the wavelength when I'm given the values to calculate the fundamental frequency of a string?

I've got equations such as:

L=lambda/2 * n, v = f * lambda (Maybe I'm missing one?) I don't know how to use them in this event.

Any hints?

Do you know what the meaning of the variable $n$ is in the expression relating $L$ and $\lambda$?

Just been looking over it again. I believe it's the harmonic number.

Do I get the wavelength by Lamda = L

And I get the frequency by f = n/2L Squareroot(T/mu)?

Some people might use the phrase "harmonic number", but there is another common word that starts with "o".

As for your answer, you have two equations involving L and v, and neither one mentions mu or T, so those don't need to appear in your answer.
