Homework Help: Photoelectric Effect: Ek of Electrons

  1. May 23, 2009 #1

    I would like to know if the Kinetic Energy of electrons emitted from a metal is constant for all emitted electrons if the metal is subjected to a constant frequency of light that is higher than the threshold frequency of the metal.

    Initially I felt that the electrons have different Kinetic Energy values as they may not all have the same work function (different energy levels?).

    This is based on the equation E(kinetic):electron = E:light wave - work_function(joules)
