When a metal was exposed to photons at a frequency of 4.68× 1015 s–1, electrons were emitted with a maximum kinetic energy of 5.70× 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 8.81× 10–7 J?
