 P: 24 1. The problem statement, all variables and given/known data Use the Bohr theory to find the series wavelength limits of the Lyman and Paschen series of hydrogen. 2. Relevant equations $$\lambda$$=$$\lambda$$limit(n2)/(n2-n02) Lyman: n0=1 Paschen: n0=3 3. The attempt at a solution The solutions are 91.13 nm (Lyman) and 820.1 nm (Paschen) but I do not know the process of finding them. Thanks for any help.
 HW Helper P: 5,004 There's another equation relating the wavelength of an emitted photon to the quantum numbers $n$ and $n_0$...use that equation and take the limit as $n\to\infty$ (why does this provide the limiting value of $\lambda$? )
 P: 24 Followed your hint; got the answer. Much appreciation. Thanks again, Jim
