WebRayleigh-Jeans Notes In the Rayleigh-Jeans law derivation, a mode number (n) represents combinations of n x, n y, and n z that equal it via: n = sqrt(n x 2 + n y 2 + n z 2). The mode … WebOur results indicate that when linear and nonlinear perturbations are incorporated, this weakly nonlinear lattice will thermalize into a proper Rayleigh-Jeans distribution with a well-defined temperature and chemical potential, in spite of the fact that the underlying nonlinearity is non-local and hence does not have a multi-wave mixing representation.
In physics, the Rayleigh–Jeans law is an approximation to the spectral radiance of electromagnetic radiation as a function of wavelength from a black body at a given temperature through classical arguments. For wavelength λ, it is: The Rayleigh–Jeans law agrees with experimental results at large … See more In 1900, the British physicist Lord Rayleigh derived the λ dependence of the Rayleigh–Jeans law based on classical physical arguments, relying upon the equipartition theorem.
