### 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.

### Re: Rydberg Equation

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.
