Question
Choose CORRECT statement(s) regarding the photoelectric effect :-
Options
A.No matter how small the intensity, if photoelectric emission takes place, the emission is instantaneous.
B.The maximum kinetic energy of a photo electron does not depend upon the intensity of incident light, if frequency of incident light is kept constant
C.Threshold frequency depends upon the intensity of incident light
D.The photoelectric current is inversely proportional to the intensity of incident light and is independent of its frequency.
Solution
K.Emax = (hv - w)
(independent of intensity of incident light)
Photoelectric current increases with intensity of incident light upto saturation value.
(independent of intensity of incident light)
