A hydrogen atom in an excited state absorbs a photon of wavelength 434 nm. What were the initial and final states of the hydrogen atom?
1/λ=1/91.127 * (1/nf2-1/ni2)
The Attempt at a Solution
Tried to use the equation, but keeping the initial and final n's as just 1/n2. can find a value for n2, but still have two unknowns (initial and final n level) and only the one equation
