The set of the thermal photons interacts only with the atomic electrons (they are continuously produced and absorbed by these electrons), and this interaction lasts as long as there is heat inside that NM. There is a common component between these two media which are characterized by a permanent interaction - the atomic and photonic media - namely, the fact that the energy is continuously distributed on the medium’s elements, but, because the energy carriers are much different, we shall be dealing with other distribution types of the energy stockpile across the elements of that particular medium. As for the energy distributed on the elements of the photonic interstitial medium, we shall have Plank’s distribution, and for the energy distributed on the elements of the atomic or molecular medium we shall have Maxwell distribution.
