Title: Figuring our quantum number?
Post by: stridder on October 02, 2008, 11:10:15 PM
Can someone please show me how to solve this question?  ???
Thanks so much  ;D

A one-electron species will absorb 11.401 nm light and undergoes a transition from the n=1 level to the n=3 level. When this species is in the n=5 level and emits 142.51 nm light, what is the quantum number for this final level?
