In quantum mechanical terms, this occurred because the maximum kinetic energy of the namesake particles depends on the work function of the material and the frequency of EM radiation used, not intensity.
This phenomenon was first seen in an experiment that used a spark between two ends of a copper receiver loop to detect generated electromagnetic waves.

For 10 points, name this effect seen when light above the cutoff frequency strikes a metal plate and creates a current between the plate and a cathode.
