1) An atom originally in an energy level with E = -8.85 eV absorbs a photon that has wavelength 738 nm. What is the internal energy of the atom after it absorbs the photon?
2) An atom initially in an energy level with E =-1.23 eV emits a photon that has wavelength 360 nm. What is the internal energy of the atom after it emits the photon?
