From Einstein's photoelectric equation, this graph is a straight line with the slope being a universal constant. This slope has the value of h/e. In an effort to disprove Einstein, Robert Millikan ... WebEinstein’s theory of photoelectric effect is based on the revolutionary idea of Planck that light was a particle. The energy transferred to every light particle, quanta or photon …
