# Deriving values from experimental data (algebra help)

1. Oct 7, 2012

One more question -

I'm working on a problem in which I need to determine the values of R and p in the equation:

${E_{B} = -RZ^{2}n^{p}}$

Where Z is 1 (we're using a hydrogen atom), and n is the principle quantum number of the electron. I know p is 2, but the point of the exercise is the determine its value from experimental data.

So I've used

http://physics.nist.gov/PhysRefData/ASD/levels_form.html

To get the binding energy levels from experimental data, and according to the problem, this should be enough information to derive values for R and p in the above equation, but I've tried and failed to do so. Can anyone show me how it might be done?

Cheers!

Think about plotting the data on a log-log plot. How would you determine R and p on such a plot?
