  1. Feb 10, 2014 #1
    1. The problem statement, all variables and given/known data

    Please see the picture.

    2. Relevant equations

    How do they get this derivation?

    3. The attempt at a solution

    I know that lambda = 2L/n and f = nV/2L so I can somewhat rearrange it myself, but I do not know where the square root is coming from.
