Q.
If intensity of incident light is increased in PEE then which of the following is true
A) Maximum $K.E.$ of ejected electron will increase
B) Work function will remain unchanged
C) Stopping potential will decrease
D) Maximum $K.E.$ of ejected electron will decrease
Explanation
(b) With the increase in intensity of light photoelectric current increases, but kinetic energy of ejected electron, stopping potential and work function remains unchanged
