Question

State the Planck's Quantum theory of electromagnetic radiation. ​

Answer 1

Planck's quantum theory. According to Planck's quantum theory, ... The smallest amount of energy that can be emitted or absorbed in the form of electromagnetic radiation is known as quantum. The energy of the radiation absorbed or emitted is directly proportional to the frequency of the radiation.

Answer 2

Answer:

The main postulates of this theory are:-

1. The energy is absorbed or emitted by a body in the form of small packets.
2. Each packet of energy is called a quantum and in case of light, the quantum of energy is called photon.
3. The energy of a photon depends upon the frequency of the radiation.
4. A body can absorb or emit only one Photon or some whole number multiple of it .
