Light with a wavelength of 190

NettetThe 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. Nettet13. mar. 2024 · In this section, we define the parameters of the triangular cross-section photonic crystal.
