A) Cut-off frequency decrease
B) Stopping potential decrease
C) Time delay for emission of photoetectron decrease
D) Saturation photocurrent increases
Correct Answer: D
Solution :
Intensity cannot change the cut off frequency or stopping potential. High intensity means more number of photons, so chances of hitting to electron by them increase and hence more photoelectron are emitted i.e., photocurrent increases.You need to login to perform this action.
