Hi Chris...I didn't even know about that page...was making my own formula sheets. Doh!
I have found find some that some of the formulas have some caveats like, the formula week 3 Rydberg constant already has hc in it thus need to be aware of this when Hf = Em-En, find for
λ, thus hc/λ =
1/λ = Ryhc/hc(1/n^2 - 1/M^2) thus the hc in Ry will cancel, but this is not stated. Appears they want use to research!
Go figure
