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. This law predicted an energy output … See more • Stefan–Boltzmann law • Wien's displacement law • Sakuma–Hattori equation See more • Derivation of Rayleigh-Jeans law • Derivation of modes a wave in a cube See more WebPlanck's radiation law. A law of physics which gives the spectral energy distribution of the heat radiation emitted from a so-called blackbody at any temperature. Discovered by Max Planck, this law laid the foundation for the advent of the quantum theory because it was the first physical law to postulate that electromagnetic energy exists in ...
