You get from the second to the first by assuming that the energy is quantised - i.e. Existing in little packets.

What is meant by energy is quantized ?

E=nhv

Where n is an integer, h is Plancks constant and v is the frequency of the oscillator. By applying this to the classical distribution for states he arrived at the Planck distribution.

E=nhv

Where n is an integer, h is Plancks constant and v is the frequency of the oscillator. By applying this to the classical distribution for states he arrived at the Planck distribution.

You mean we mean that he assumed the Particle nature of light ?

He didn't quite go that far. Einstein is given credit for that.

He didn't quite go that far. Einstein is given credit for that.

But at least he assumed that the light is quantized to photons.

Planck's postulate was that the energy of oscillators comes in discrete packets given by:

E=nhv

Where n is an integer

N is number of oscillators ?

No, I don't think he went that far. It was a mathematical trick that gave the right answer.But at least he assumed that the light is quantized to photons.

No, it is just an integer. The number of oscillators is given by the Boltzmann distribution.N is number of oscillators ?
