### Rydberg Equation

So I know that we aren't taught the Rydberg Equation in class but should we still learn it ourselves? Are we allowed to use it on tests?

### Re: Rydberg Equation

Hi, the Rydberg Equation is just a derivation of ΔEn = Efinal - Einitial, with En = -hR/n^2. In other words, it is just the simplified form to find the change in energy from one energy level to another for the frequency or 1/λ. The professor wanted to show how this formula was derived, but I think it should be fine to use on tests.

Is there any difference in using the two (like would one be more intuitive or simpler to use)?

Will this equation be given to us on tests?

### Re: Rydberg Equation

This has become a string of questions for now, but to (hopefully) answer most of the questions, one of the UAs told me that Dr. Lavelle prefers that we use the En = -hR/n^2 equation over the other one because it makes more sense conceptually. In this manner, we won't learn the other version but I think we are expected to know the equation aforementioned.
