Question
A photon of energy hn is absorbed by a free electron of a metal having work function w < hn. Then :
Options
A.The electron is sure to come out
B.The electron is sure to come out with a kinetic energy (hv - w)
C.Either the electron does not come out or it comes with a kinetic energy (hv - w)
D.It may come out with a kinetic energy less than (hv - w)
Solution
Photoelectric effect is a random phenomena. So, electron It may come out with a kinetic energy less than (hv - w) as some energy is lost while escaping out.
