Problem
The ground state of a certain atom has energy −5.2 eV relative to the continuum (0 eV). The atom absorbs a photon of wavelength 410 nm and the electron is just barely ionized (it leaves with negligible kinetic energy). Determine the energy (in eV) of the bound state from which the electron was removed.
