ANSWER:
Solution: Step1: According to Planck’s quantum theory of radiation, radiant energy is not emitted or absorbed continuously but discontinuously in the form of small packets of energy called quanta. The amount of energy associated with a quantum(in case of light, the quantum of energy is often called photon) of radiation is proportional to the frequency of light, E = h , where h is a universal constant called Pl
