### Atomic Spectra

Hi all!
Has anyone completed problem 1A.15? How do find the initial and final values of n when given the line observed at 102.6 nm?
Thanks!

Well, first you would have to find the frequency using the equation v(nu) = c/ λ. and that would give you 2.922 x 10-15 s-1. Then you would have to use Rydberg's equation to solve for n2.
