### Rydberg Equation Alternatives?

Posted:

**Sat Oct 12, 2019 5:09 pm**Hi all,

I'm currently working on the homework from section 1A when I came across an interesting problem, 1A.15. The problem states that "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 consulted the Student Answers Manual and saw the answer was found using the Rydberg Equation. However, I recall Dr. Lavelle saying we wouldn't be using that equation in his class. I was curious if there are any alternate ways I should be able to solve this problem, or if this sort of question wouldn't appear on an exam? Please let me know your thoughts. Thank you and I hope you have a nice weekend!
