WebThe photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics. WebJul 6, 2024 · If we concentrate between the cutoff and the saturation regions of the I-V graph, we can see that at any given applied voltage, the photocurrent from the case with light freq f2 is higher than that with f1.
