Hello everyone, I am doing some physics questions with Rydberg's equation and am having some trouble. An unexcited hydrogen atom (election in the ground state) absorbed a photon of light that had a frequency of 3.09 x 10^15 Hz. Through what transition did the election in this atom undergo? What I did so far was convert the frequency into wavelength with was 9.7 x 10^-8m. and I know Rydberg's constant is 1.10 x 10^7, but I end up with two variables n variables. I am not quite sure where to go with this unfortunately. Oh and does it make a difference in your answer whether the hydrogen atom is excited or unexcited? Thanks in advance for the help!
