When a metal was exposed to photons at a frequency of 1.34×1015 s−1,
electrons were emitted with a maximum kinetic energy of 3.60×10−19 J.
Calculate the work function, Φ,
of this metal.
Φ=
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 3.67×10−7 J?
number of electrons:
