### Rydberg's Equation

Can someone explain when you would use Rydberg's Equation / what types of questions you use it in?

### Re: Rydberg's Equation

We would use this equation in questions that ask us about a change in energy levels (n1 to n2). i.e. How much energy is required to excite an electron from energy levels 1 to 4? If ##J energy were used to excite an electron off of ground state, what will be the final energy level of the electron?

From what I noticed, you mainly use the Rydberg Equation in questions that ask about the electronic transition levels, so when the electron goes from n=1 to n=3 state for example.

### Re: Rydberg's Equation

You use Rydberg's equation when the question talks about an electron transitioning from one energy level to another. Generally, you will use it to sole for the final or the initial energy level, based on the information that is provided. Sometimes, you will also be asked to calculate the frequency of light emitted/absorbed when the energy levels are given. I heard Lavelle say in class, though, that we should try to use the energy equation (E = -hR/n^2) as much as possible because you will better understand the concepts than if you stick to using the Rydberg equation.

Can someone explain why Lavelle preferred us to us this equation, (E = -hR/n^2), instead of Rydbergs equation?
