Rayleigh-jeans law ppt
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 that diverges towards infinity as wavelength approaches zero (as frequency tends to … See more 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: 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 WebThe meaning of RAYLEIGH-JEANS LAW is an approximation in respect to thermal radiation: the emissive power of a blackbody at absolute temperature T and at a given wavelength λ …

WebAfter this, he was joined by Sir James Jeans in the year 1905. Initially, Lord Rayleigh claimed the λ depends on the Rayleigh - Jeans law. That was concluded on the basis of arguments made by classical physicists and various empirical facts. This law was explained more clearly in the year 1905 by both Lord Rayleigh and Sir James Jeans.
