    Finding Work function and Plank constant

    Homework Statement In experiments on lithium, Millikan observed a maximum kinetic energy of 0.550eV when electrons were ejected with 433.9nm light. When 253.5nm light was used, he observed a maximum kinetic energy of 2.57eV. Using these results find a) the work function for lithium, and...
