Question

(B) No. When a photon interacts with an electron,the electron absorbs the energy of the photon. However,for the electron to be emitted from the metal

Vedclass · Accepted Answer

No,only those electrons are emitted which absorb energy from incident photons,more than their binding energy.

Vedclass · Answer

(B) No. When a photon interacts with an electron,the electron absorbs the energy of the photon. However,for the electron to be emitted from the metal surface,it must overcome the work function (binding energy) of the metal. If the energy absorbed by the electron is less than the work function,the electron will not be emitted; it will instead lose its energy through collisions with other atoms within the metal and eventually settle back into a lower energy state. Therefore,only those electrons that absorb energy greater than their binding energy are emitted as photoelectrons.

Do all the electrons that absorb a photon come out as photoelectrons?
