How do I calculate Energy?

[whatisphysics]

1. The problem statement, all variables and given/known data

I made a word doc, and attached it as a picture.

2. Relevant equations



3. The attempt at a solution
I calculated all the wavelengths, and plotted the values, but how do I find energy from the equation deltaE = hv?
Thanks in advance!

Looks to me like just a plug and chug, I am not sure what's the problem.

But what is the R, and what is the c?

thanks.

R is what you are to find from the plot (so called Rydberg constant), c is the speed of light.

R2 mentioned on the plot seems to be a correlation coefficient, this can be confusing.
