Rayleigh–jeans law derivation
WebMar 5, 2024 · 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 … WebWien's law, also known as Wien's displacement law, was developed in 1893 and asserts that black body radiation has various temperature peaks at wavelengths that are inversely proportional to temperatures. The following is a mathematical version of the law: λmax = b T λ m a x = b T. where b = 2.8977 x 10 3 m.K is the Wien's displacement constant.
