### Clarification on Rydberg's Constant

Today in lecture Lavelle went over Rydberg's constant. I understand that it has to do with hydrogen, but can someone explain exactly what it is used for?

### Re: Clarification on Rydberg's Constant

Rydberg's Constant is used in the equation En=-hR/n2

The equation is used to find the energy released (or absorbed) when an electron either drops in energy or jumps in energy level.
*Keep in mind that the energy should be negative if the electron is losing energy (dropping in energy level) and positive when the electron is gaining energy (jumping in energy level).
