Yes, the Rayleigh-Jeans formula- as we know it today - is an approximation of Planck's formula for very large lambda values as stated in some wikipedia articles $$I(\lambda,T)=\frac {8 \pi h c}{\lambda^5} \cdot \frac{1}{e^{\frac{hc}{\lambda k_B T}} - 1} \approx \frac{8 \pi k_B T}{\lambda^4}...

The search for a mathematical formulation that would explain the shape of the blackbody radiation (which experimentally has that famous ‘bell-shaped’ as a function of wavelength, i.e. zero for wavelength values tending to zero as well as for those tending to infinity) was attempted for several...

Hello I have some doubts about the relationship between the probability of occupying an electronic state defined by the Fermi Dirac distribution and the relationship to the number N of free electrons in a solid of N atoms. In particular I refer to the Section 2.2 of Solid State Physics...
