A ground state hydrogen atom absorbs a photon of light having a wavelength of 92.30 nm. It then gives off a photon having a wavelength of 1820 nm. What is the final state of the hydrogen atom?

OpenStudy (anonymous):

energy provided=13.4 eV energy released=0.7 eV energy absorbed = 12.7eV initial energy= -13.6eV [ground state] final energy = -13.6+12.7 = -0.9 eV This energy corresponds to n=4 in hydrogen atom
