A) No electrons are emitted if \[\nu \] is less than Wl h, -where W is the work function of the metal
B) The ejection of the photoelectrons is instantaneous.
C) The maximum energy of the photoelectrons is hi).
D) The maximum energy of the photoelectrons is independent of the intensity of the light.
Correct Answer: C
Solution :
[c] According to photo-electric equation : \[K.E{{.}_{\max }}=hv-h{{v}_{0}}\] (Work function) Some sort of energy is used in ejecting the photoelectrons.You need to login to perform this action.
