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