Given below are two statements:
Statement I: The photoelectric effect does not takes place, if the energy of the incident radiation is less than the work function of a metal.
Statement II: Kinetic energy of the photoelectrons is zero, if the energy of the incident radiation is equal to the work function of a metal.
In the light of the above statements, choose the most appropriate answer from the options given below.
Text Solution
Verified by ExpertsD
The minimum energy required to eject electrons from a metallic surface, must be equal to the work function of that metal. According to Einstein's photoelectric equation, kinetic energy of the emitted electrons is K.E. 
If 
, then K.E.
