Reference no: EM13186720

An electron in an excited state of a hydrogen atom emits two photons in succession, the first at 1281 nm and the second at 102.5 nm, to return to the ground state (n=1). For a given transition, the wavelength of the emitted photon corresponds to the difference in energy between the two energy levels.
