### Calculate values of n

Hey guys,
So I calculated the wavelength, but I don't know where to go from there.
Problem 1A.15 7th edition. In the ultraviolet spectrum of atomic hydrogen, a line is observed at 102.6 nm. Determine the values of n for the initial and final energy levels of the electron during the emission of energy that leads to this spectral line.

### Re: Calculate values of n

In this problem they give you the wavelength so you use the equation $\nu =c/\lambda$ to find the frequency. Then you want to use the Rydberg equation which is $\nu =R(1/n_{1}^{2}-1/n_{2}^{2})$. Your n1 value will be 1 because it is in the uv spectrum so it is a part of the Lyman series. From there you just solve for n2

If you look at example 1A.2 in the book, your work process should be exactly like the example but backwards. Because you are given wavelength, you can solve for frequency and plug it back into the Rydberg equation to solve for n₂
