The Quantum of Radiation or A Threshold of Action?
Etkin Valery
Abstract
This article refutes the assertion, based on an examination of the photoelectric effect, that Planck'sconstant is universal, as well as the quantum mechanics that underlies it. Several errors in the energybalance equation for the photoelectric effect are revealed. It is shown that the quantum yield influencesPlanck's constant. The need to account for the efficiency of photovoltaic energy converters (PVCs) andtheir relationship to quantum yield is substantiated. The true meaning of a radiation quantum as theenergy required to maintain the "idle" state of a PVC is established, along with its dependence on thetype of photocathode and its operating mode. Based on this, a classical explanation is given for the lawsof the photoelectric effect discovered by A. Stoletov, and the conclusion is drawn that it is erroneous tocontrast it with the laws of quantum mechanics.
