Rayleigh equation formula
WebFormula. The Rayleigh-Jeans law approximates the spectral radiance of a black body as a function of its wavelength at a given temperature. The Rayleigh-Jeans equation can be … WebInstability starts once the local Rayleigh number – here the scaled linear Rayleigh number – reaches a given critical value that depends only on the conditions at the modulated surface. The most dangerous mode has a wavenumber inversely proportional to the only relevant scale of the system, $\delta \sim \omega ^{-1/2}$ , in agreement with figures 3 ( c , d ) and …
