Question

What are the main postulates of Planck Quantum Theory?

Answer 1

Hint: To solve this question, we need to be in brief discussion about the origin of the Planck Quantum theory. So, we can discuss the postulates of Planck Quantum Theory as well as other test cases and uses of this theory.

Complete step-by-step solution:
The matter always radiates energy or absorbs energy in discrete quantities discontinuously which are in the form of the small packets or bundles.
The energy of the matter that is absorbed or emitted is directly proportional to the frequency of the radiation.
The researchers performed many experiments to analyze Planck's quantum theory. As a result of this, all experimental observations were supported and worked as strong evidence for quantum theory and showed that energy of electron motion in matter is quantized. The light is separated by a prism according to their wavelengths. If light behaves only as a wave, then prisms should produce a continuous rainbow. This also supports Planck's Quantum Theory. The emission spectrum of nitrogen gas also supports this theory of radiation.
There are $3$ main postulates in Planck's Quantum theory; they can be explained as follows:
 Energy is emitted in the form of small potions or packets known as quanta as opposed to the previously proposed idea of a continuous wave. The frequency of the radiation emitted always determines the energy of each quantum of energy.
The total energy absorbed by anybody or surface is equal to the sum of the energies of all quanta of energy.

Note: Max Planck's quantum theory provides a detailed description of the physical properties of all substances at the scale of atoms and subatomic particles. It can include quantum chemistry, quantum field theory, and quantum technology and quantum information science.
