### Rydberg

When would we incorporate the -R[1/n1^2 - 1/n2^2], or which problems would call for this equation?

You would use this equation when trying to find the wavelength of a electron that has gone from a high energy level (n2) to a lower energy level (n1). Hope this helps :)

### Re: Rydberg

The Rydberg formula is used to predict the wavelength of light resulting from an electron moving between energy levels.

### Re: Rydberg

In addition, since we are solving for wavelength in this case, it can be extended to equations such as E=lambda X mu (energy=wavelength times frequency) and other equations that we will need to know for the test. It is very important that we know how to relate different formulas to each other by messing around with the algebra; Professor Lavelle discussed this by explaining how to derive the formulas.

According to the TAs, this is more important on the midterm than the upcoming test so keep that in mind.

Best,

would use for wavelength but can also be manipulated for other uses
