planks quantum theory :

✲ In order to explain black body radiation , Max planck prsented a new theory known as quantum theory of radiation.

postulates :

✯ Emmission of radiation from a body is due to the vibrations of the charged particles in the body .

✯ Radiation is associated with energy .

✯ The radiant energy is emitted or absorbed by a body not continuously but discontinuosly in the form of small packets of energy called quanta .

It is directly proportional to the frequency of light.

E ∝ v or E = hv

where 'h' is known as plancks constant .

The value of 'h' is 6.6256 × 10 ^ -34 J.sec .

✯ The total amount of energy emitted or absorbed by a body will be some whole number multiple of quantum , E = nh v , where n is an integer such as 1 , 2 , 3 ...... This means that a body can emit or absorb energy equal to hv , 2hv , 3hv , ...... This is called quantization of energy .

✯ The emitted radiant energy is propagated in the form of waves .
