given the wavelength of photon absorbed by H atom and wavelength of photon emitted by that H, find the final "n" state of H atom.

2. Relevant equations

E=nhf

3. The attempt at a solution

I tried... n1hf1=n2hf2

n1f1=n2f2

where n1=1

so: f1=n2f2

1/lamdba1=n2(1/lambda2)

and I get an integer value for n. But how is that the right way? Because I thought n was the number of photons... so it doesn't make sense for me to be solving for n :( I tried using the Rydberg equation, first plugging in the first lambda given to figure out what level of energy H atom initially got excited to but I didnt get an integer...
