### Formulas?

Can anyone clarify which equations we need to know? I'm kind of lost with the Rydberg expression v=R(1/n21-1/n22), Weins Law, and the Bohr Frequency condition: hv=E(upper)-E (lower).

Dr. Lavelle's Quantum World Lecture Outline on his website specifies which equations we need to know.

He also mentioned that he really does not want us using Rhydberg's equation because there's more room for error. He wants us to use E = -hR/(n^2) for each energy level and then go E(final)-E(initial) so that we actually understand the problem and don't get positive and negative signs mixed up. Someone correct me if I'm wrong!
