How to derive Mersenne's fundamental frequency formula?

  1. Feb 18, 2016 #1
    I'm talking about equation 22,


    Does anyone know how to derive this? It's Marin Mersenne's formula for fundamental frequency, but I'm perplexed as to how he derived it.

    L would be the length, F would be force, and μ would be mass per unit length.
    f is the frequency

    I don't know your source. Can you specify what is given to derive it from?
