NEET 2009 Physics question
The number of photo electrons emitted for light of a frequency (higher than the threshold frequency ) is proportional to:
Answer: (2)
Solution
Each photon ejects at most one electron, so for a given frequency above threshold the number of photoelectrons emitted per second is proportional to the number of photons incident per second, i.e. proportional to the intensity of the light (the saturation photocurrent
