WebbThe law of the photoelectric effect describes that the incident photon requires the energy for releasing electrons from the surface and that the kinetic energy depends on the intensity of the incident photon on the surface. E=W+KE. hv=W+KE, therefore, KE=hv-W. From the above equation, it is clear that the kinetic energy of the radiated electron ... WebbThe photoelectric effect was first noted by a French physicist, Edmund Bequerel, in 1839, who found that certain materials would produce small amounts of electric current when …
