When a metal was exposed to photons at a frequency of 1.43 x 10¹5 s-¹, electrons were emitted with a maximum kinetic energy of 3.40 x 10-19 J. Calculate the work function, D, of this metal. 6= J/photon What is the maximum number of electrons that could be ejected from this metal by a burst of photons (at some other frequency) with a total energy of 7.59 x 10-7 J? number of electrons:
