If light with photon energy 2eV is incident suitably on the surface of a metal with work function 3eV, then
-
A.
no electron will be emitted -
B.
the few electrons emitted will have a maximum kinetic energy of 1eV -
C.
the few electrons emitted will have a maximum kinetic energy of 3eV -
D.
many electrons will be emitted
Correct Answer: Option A
Explanation
An electron can only be emitted if photon energy is equal or greater than work function of the plate
