Rayleigh's law

WebBoth equations are in fact structurally similar with Abbe limit given by d = λ 2 N A. And Rayleigh limit given by d = 1.22 λ 2 N A = 0.61 λ N A. where lambda is the wavelength and N A the numerical aperture of the light collecting lens. The factor 1.22 comes from the definition of Bessel function of 1st kind,the fact that 1st minima of the ... WebNov 23, 2024 · $\begingroup$ The problem I mention above makes the whole derivation of the Rayleigh-Jeans law come to a screeching halt long before you can even consider the secondary problem of the UV catastrophe. The UV catastrophe comes from an equation whose very derivation is invalid for the reasons I mentioned. The reason why I'm not …

WebJan 19, 2024 · I'm reading about why the Rayleigh-Jeans formula failed to explain blackbody radiation curves. The Rayleigh-Jeans formula: $$ E = kT\left(\frac{8\pi\nu^2}{c^3}\right) $$ I see explanations saying that the part of the equation in parentheses related to the "number of standing waves that are able to fit into a blackbody cavity". WebAccording to Rayleigh Jeans radiation waves in black body can be compared to the standing waves in cubical cavity.
