### Rydberg Equation

How and in what situations would you use the Rydberg equation?

### Re: Rydberg Equation

The Rydberg formula is used to calculate the wavelength of light produced by an electron that is moving between energy levels (between orbitals). So, when a question surrounds the movement of electrons between different orbitals (AKA there is a change in energy), you apply Rydberg's formula, plugging in for nf (the final quantum number) and ni (the initial quantum number).

### Re: Rydberg Equation

Lavelle advised us not to use Rydberg's Equation because it's easier to understand what's going on if you calculate the energies at both the levels (using E= -hR/n^2) then subtract the initial from the final.

### Re: Rydberg Equation

The Rydberg equation can also be seen in the change in energy formula, where energy initial is subtracted from the energy initial.

The Rydberg equation's purpose is to find the change in energy (noted by Doctor Lavelle to be for an H-atom).

### Re: Rydberg Equation

You use rydberg's equation if you need to calculate the energy level of a hydrogen atom. at any level equal to n.
