Photoelectric experiment is conducted separately in the same experimental set up using light of same intensity but of different frequencies $$f1$$ and $$f2$$ $$f1$$$$f2$$. If i be the photo current and V be the applied potential, then which of the following graphs correctly shows the variation of i with V?

Question

Photoelectric experiment is conducted separately in the same experimental set up using light of same intensity but of different frequencies $$f1$$ and $$f2$$ $$f1$$>$$f2$$. If i be the photo current and V be the applied potential, then which of the following graphs correctly shows the variation of i with V?

Infinity Learn · Accepted Answer

Maximum photo current depends upon the number of photo electrons ejected which in turn depends upon the intensity of the incident light. Again stopping potential is given by e (stopping$$ $$potential) $$=hf$$−ϕ. Hence (4) is the correct option.
