## Homework Statement

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?

## Homework Equations

1/λ=1/91.127 * (1/n

_{f}

^{2}-1/n

_{i}

^{2})

## The Attempt at a Solution

Tried to use the equation, but keeping the initial and final n's as just 1/n

^{2}. can find a value for n

^{2}, but still have two unknowns (initial and final n level) and only the one equation
