Among the following, the one that is not a characteristic of Planck’s quantum theory of radiation is
1 Radiations are associated with energy
2 Magnitude of energy associated with a quantum is equal to \({{\rm{h}}^{{\rm{1/2}}}}\)
3 Radiation energy is neither emitted nor absorbed continuously
4 A body can emit less or more than a quantum of energy
Explanation:
According to Planck's quantum theory, a body must emits radiation with the same energy as that of absorbed.
