When a metal was exposed to photons at a frequency of 1.17x1015 s-1, electrons were emitted with a maximum kinetic energy of 3.30×10-19 J. Calculate the work function, , of this metal. 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 7.65x10-7 J?
