Question

There are two light sources A and B. The intensity of source A is more than that of B and the frequency of light emitted by source B is higher than that of A. The photo electric current obtained will be more from source(Assume that both the frequencies are greater than the threshold frequency of the metal on which these lights will be incident)

Solution

The correct option is A A
Answer is (B).
Photo electric current increase with increase in intensity as more the intensity of light, more will be the number of electrons hitting surface and more will be the number of ejected electrons.
Hence photo electric current of A is more than that of B.
