WebSo IA = E/Δt, where E = nhf (n photons of frequency f) Let's say each photon is able to pull out one electron from the plate, so the current i = ne/Δt, where e is the charge of the electron. That gives n/Δt = i/e, and IAe=hfi -> i = IAe/hf, so when we increase the frequency, if the intensity of the radiation remains the same, the current decreases. WebPlot a graph of the results and you get: Obviously, nothing happens unless you get photons with energy above the threshold value, f o. After that, increasing the frequency of the photons increases the maximum kinetic energy of the photoelectrons so stopping them takes a larger value of stopping potential. The gradient of this graph is .
