Explain the max planck's quantum theory and black body radiation.
Step 1: Definition of black body
Step 2: Max Planck's quantum theory:
According to Planck, an oscillator can have a discrete set of energies that are integral multiples of a finite quantum of energy
where, is an integer or zero, is the Planck's constant and is the frequency.
Planck assumed that the change in energy of the oscillator due to emission or absorption of radiation can also take place by a discrete amount .
The value of
Step 3: Planck's law of blackbody radiation:
