Free What is the number of voltage for stopping Photoelectric voltage to repeal electrons? Animation

The stopping voltage in the photoelectric effect is the voltage needed to stop the ejected electrons from reaching the anode. When light strikes a metal surface, it releases electrons, and the stopping voltage is the negative voltage applied to the anode that cancels out the kinetic energy of the ejected electrons, preventing them from moving further. The required stopping voltage is related to the energy of the incoming photons minus the metal's work function.
