Homework Help: How to calculate 1st Overtone Frquency

  1. Jun 4, 2015 #1
    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 [itex]n[/itex] is in the expression relating [itex]L[/itex] and [itex]\lambda[/itex]?

    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.
