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. WebThe plot shown in Figure 8.8, namely, ln ⁡ (J / T 2) versus δ, is generally known as the “Fowler plot.” Fitting the observed photoelectric data to this plot, one can obtain the characteristic frequency ν 0 and hence the work function ϕ of the given metal.
