Chemistry Question on Structure of atom
In the photoelectron emission, the energy of the emitted electron is
A
greater than the incident photon
B
same as that of the incident photon
C
smaller than the incident photon
D
proportional to the intensity of incident photon
Answer
smaller than the incident photon
Explanation
Solution
In the photoelectric effect, the energy of the emitted electron is smaller than that of the incident photon because some energy of photon is used to
eject the electron and remaining energy is used to increase the kinetic energy of ejected electron.
