### 1.15 Homework Question

Posted:

**Wed Oct 11, 2017 12:20 pm**Hey guys,

The question for chapter 1 number 15 is:

In the ultraviolet spectrum of atomic hydrogen, a line is observed at 102.6 nm. Determine the values of n for the initial and final energy levels of the electron during the emission of energy that leads to this spectral line.

I already found the frequency, but when I tried to use Rydberg's equation to solve for n, I was confused because there are 2 different values for n (n1 and n2) and I was just wondering how you were supposed to solve this when you do not have either n1 or n2 to start with. When I checked the solutions manual, they assigned n1 to be 1, and I am confused on how they got to that conclusion.

Thanks!
