The Duane-Hunt law can be used to calculate the maximum frequencies observed from an inverse form of this effect. It was first seen in an experiment performed in a dark box, where the area between two brass conductors formed a spark gap, but the same could not be said for glass or quartz when UV light was shone on them. This effect is only observed in materials whose work function is less than the energy of incident particles, and the difference in those quantities gives the kinetic energy of particles emitted. Sometimes named for its discoverer Heinrich Hertz, for 10 points, name this effect in which photons striking a metal result in an emission of electrons.
