Answer :

The major establishment from the photoelectric effect was, light also shows particle nature.


a. Einstein said that, light consists of photons (small packets of energy). When a beam of photons interacts with electron, then it no longer exists after transferring all the energy to electron and is used to knock out the electron.


Some amount of energy is used as Work function is used and rest is converted into kinetic energy of electron



where,


h =energy of proton


h=Planck’s constant


frequency of proton


=work function


=kinetic energy of electron


b. Greater intensity has no effect on kinetic energy of an electron. This cannot be explained by wave theory. Also wave theory cannot explain the existence of threshold energy too.
