In this problem it gives us the wavelength of 102.6nm and tells us the line is in the UV spectrum. This means that n1 is going to = 1, and we must find n2. v=R((1/n1^2)-(1/n2^2)), and wavelength 102.6nm = c / v. I just don't know the algebra to find the value of n2. Thanks for the help
After converting the wavelength of the spectral line to the energy it emits, you have to use E=E(final)-E(initial) to figure out the n values.You're already given the n value for the final energy as UV follows the Lyman series stating from any n value, the electron must return to ground state at n=1. Next, you find the Energy for the final and then plug all of the given information into the change in E equation in order to isolate n for the initial energy. Isolating n of the initial energy will give you the last n value.
