MHT CET 2024 Physics question
The number of photoelectrons emitted for light of frequency (higher than the threshold frequency ) is proportional to
Answer: (B)
Solution
When the frequency exceeds the threshold frequency, photoemission occurs. The intensity of light is proportional to the number of photons incident per second, and each photon ejects (at most) one electron, so the photocurrent, i.e. the number of photoelectrons emitted per second, is directly proportional to
