Photoelectric effect graph slope
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 … WebIn his explanation of the photoelectric effect, Einstein defined a quantized unit or quantum of EM energy, which we now call a photon, with an energy proportional to the frequency of EM radiation. In equation form, the photon energy is. E = hf, 29.4. where E is the energy of a photon of frequency f and h is Planck’s constant.
