The quantum theory of plong
According to this theory, the emission or absorption of radiation energy by matter is dissolved rather than continuous, that is, the emission or absorption of radiation energy is in the form of small packets of certain energy / quanta of these packets of energy or If the frequency of radiation is v, then the energy of each photons quantum is hv where h is the Planck constant.
Thus the radiation energy emitted or absorbed by the material E = nhv
Where n = 1,2,3 ……… and it is called quantum number
In this way, the plant gave a quantum theory of energy.
