Abstract
In the early XX century, physicists accepted that Einstein’s photoelectric equation was a profound move toward the quantum mechanical description of energy and matter and it is one of the critical equations leading us to quantum physics and mechanics. But looking today the photoelectric effect couldn’t be formulated perfectly because the proportionality constant h/e in the equation is linear regression in the very short interval of frequency. Of course, at that time it was. Even now, not only the photoelectric effect but many phenomena haven’t been explained in the aspect of classical physics because of that they are not linear, but cyclical. The photoelectric effect hasn’t been possible to describe precisely without the open hysteresis of the magnetism. In this paper, the open hysteresis of the photoelectric effect, the Fermi-Dirac distribution, the intensity of the quantum photoelectric effect, the saturation, the influences of the various materials on it, and the area of the hysteresis loop are presented. I examine models that can be solved exactly with the tools of mathematics so that neither approximations nor computer simulations are required.
