I don't understand what stopping potential is, how is it work and why it is needed. It says in the book that it makes the current zero but I don't understand how is this related to photoelectricity. Thank you so much!?

Light is comprised of photons each conveying quanta of vitality relative to recurrence, E = hf Additionally, c = f(lambda), however, c is consistent, so differing the wavelength will change recurrence which changes vitality. So assembling everything, E= hf/A Light of higher vitality will give electrons a more noteworthy active vitality enabling it to beat the contradicting power by the potential. Halting voltage: The voltage YOU should APPLY (battery/control pack or something) that keeps electrons from achieving the anode (the work it applies is more noteworthy than the most extreme motor vitality of electrons). No electron achieving anode = no electron stream. Most extreme dynamic vitality: The name justifies itself with real evidence; the greatest active vitality of a photoelectron (an electron discharged by the photoelectric impact) Work: The Base measure of vitality required for an electron to be discharged from a metal. Limit recurrence: The Base recurrence of a photon, that would convey vitality proportional to the WORK Capacity making an electron be produced.
