The ground state energy of an atom is -1...

The ground state energy of an atom is `-13.6eV`. The photon emitted during the transition of electron from `n=3` to `n=1` state, is incidenet on a photosensitive material of unknown work function. The photoelectrons are emitted from the materials with a maximum kinetic energy of 9 eV. the threshold wavelength of the material used is
