w = wavelength
1/w = 1.0973E7(1/1 - 1/x^2)
Convert 93.73 nm to m and solve for x. That will tell you to which orbit the electron has been moved.
Then, 1/w = 1.0973(1/y^2 - 1/x^2).
Solve for y.
A ground state hydrogen atom absorbs a photon of light having a wavelength of 93.73 nm. It then gives off a photon having a wavelength of 1094 nm. What is the final state of the hydrogen atom?
