Understanding Bohr Theory (Wavelengths for Electron States)

  1. Mar 26, 2012 #1
    Ok, I am having some trouble with the maths regarding Bohr Theory. I understand that the orbit radius is
    where a0=0.0529

    and that the wavelength for an electron with l=0 (circular orbit), is

    so for n=1, λ=6.28a0.

    So, following the same maths, for n=2, I get λ=2x∏x2^2=8∏a0.

    However, according to http://hyperphysics.phy-astr.gsu.edu/hbase/bohr.html#c5, The answer is 4∏a0, which means that n is not squared.

    Can anyone please explain whether or not n is squared to work out the orbital radius?
