Photo Electric Effect

Question

Photoelectric experiment is conducted separately in the same experimental set up using light of same intensity but of different frequencies $f_{1} and f_{2} (f_{1} > f_{2})$ . 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?

Moderate

A
B
C
D

Solution

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) $= h f - ϕ$ .
Hence (4) is the correct option.
