WebFeb 11, 2024 · I was puzzled by the behavior of the simulation until I read the PhET Tips for Teachers of the Photoelectric Effect (same page as the software on Phet site):. In the default setting, since the intensity of light is proportional to the number of photons times the frequency, if you increase the frequency while holding the intensity constant, the number … WebOct 27, 2015 · 1. Online, I found a graph of photocurrent vs. stopping voltage: And I can’t figure out how photocurrent and stopping voltage have such a relationship. Stopping voltage is proportional to maximum KE and photon frequency, but neither of those factors really affect photocurrent as long as the threshold is reached. I would appreciate some input. WebThere are four aspects of photoelectron emission which conflict with the classical view that the instantaneous intensity of electromagnetic radiation is given by the Poynting vector S: (2) S = ( E × B) / μ 0, with E and B the electric and magnetic fields of the radiation, respectively, and μ 0 (4π×10 -7 Tm/A) the permeability of free space. howard frauwirth md wyckoff nj
