Hey there,(adsbygoogle = window.adsbygoogle || []).push({});

I'm having trouble understanding where two of the formulas for angular momentum of an electron in the hydrogen atom tie together. The first relation L = nh/(2∏) which comes from the de Broglie momentum-wavelength relation and the requirement for the electron wavelength to equal an integer number of the path circumference. The other I have come into contact with is: L = (√(l(l+1))h/(2∏) from the Schrodinger equation.

I understand the derivation of both, I just don't see how they are the same. I thought this n was the principle quantum number?

Thanks for your help!
