Rayleigh-jeans approximation
http://hyperphysics.phy-astr.gsu.edu/hbase/mod6.html WebThe Rayleigh-Jeans Law was a useful but not completely successful attempt at establishing the functional form of the spectra of thermal radiation. The energy density u ν per unit frequency interval at a frequency ν is, according to the The Rayleigh-Jeans Radiation, u ν = 8πν²kT/c². where k is Boltzmann’s constant, T is the absolute ...

I'm finally taking my Thermo/Stat Mech course and I realized that the Poisson distribution looks similar to the curve of the Rayleigh-Jean Formula for thermal radiation. Since the formula includes $\lambda^{-4}$, it has never sat well with my physical intuition because powers of $4$ are …

WebThis is known as the Rayleigh—Jeans 6 approximation.It says that in the microwave portion of the spectrum, radiance is simply proportional to temperature. In fact, in the microwave region, it is customary to divide radiance values by (c 1 /c 2)λ −4 and to refer to the quotient as brightness temperature.Brightness temperature is also used in the infrared portion of …
