Answer 1

Answer:

Explanation:

What is Planck’s Quantum Theory?

Planck’s quantum theory explains emission and absorption of radiation. Postulates of Planck’s quantum theory are as follows –

Matter radiate energy or absorb energy in discrete quantities discontinuously in the form of small packets or bundles.

The smallest bundle or packet of energy is known as quantum. In case of light, a quantum of light is known as a photon.

The energy of the quantum absorbed or emitted is directly proportional to the frequency of the radiation. So, energy of the radiation is expressed in terms of frequency as follows-

(Image to be added soon)

A body or matter can radiate energy or absorb energy in whole number multiples of a quantum as nhv. Where n is a positive integer. So, energy can be absorbed or radiated as hv, 2hv, 3hv, 4hv……etc. not in the form of 1.5hv, 2.5hv…etc.

Answer 2

Answer:

Planck's quantum theory is a natural phenomenon of quantum mechanics. ... It explains the quantum nature of the energy of electromagnetic waves. Planck's quantum theory deals with phenomena such as the photoelectric effect and the nature of radiated emission which were not explained by the laws of classical mechanics.
