Question

State the postulates of Planck's quantum theory.

Answer 1

Postulates of Planck's quantum theory:

• Matter radiates energy or absorbs 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 the 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.

$\mathrm{E}\propto \mathrm{\nu }$

Where, ‘E’ represents the energy and 'v' represents the frequency of radiation.
