Write three basic properties of photons which are used to obtain Einstein’s photoelectric equation.
Use this equation to draw a plot of maximum kinetic energy of the electrons emitted versus the frequency of incident radiation.

Three basic properties of photons :
(i) Photons are quanta or discrete carriers of S energy.
(ii)The energy of a photon is proportional to the frequency of light.
(iii) The photon gives all its energy to the electron with which it interacts.
