WebBlackbody Radiation: The Derivation. In the 19th century, the theory of blackbody radiation was one of the worst theories ever devised. It was so far off from the experiment you wonder why they even bothered. Max Planck, though, recognized that the shape of the curve was well known to mathematicians. It was just the x-value divided by an ... Planck's law describes the unique and characteristic spectral distribution for electromagnetic radiation in thermodynamic equilibrium, when there is no net flow of matter or energy. Its physics is most easily understood by considering the radiation in a cavity with rigid opaque walls. Motion of the walls can affect the radiation. If the walls are not opaque, then the thermodynamic equilibrium is not isolated. It is of interest to explain how the thermodynamic equilibrium is attain…

WebPlanck's law, which gives the correct radiation at all frequencies, has the Rayleigh–Jeans law as its low-frequency limit. Historical development [ edit ] In 1900, the British physicist Lord Rayleigh derived the λ −4 dependence of the Rayleigh–Jeans law based on classical physical arguments, relying upon the equipartition theorem . WebQuantitatively, Wien’s law reads. λ max T = 2.898 × 10 −3 m · K. 6.1. where λ max is the position of the maximum in the radiation curve. In other words, λ max is the wavelength at which a blackbody radiates most strongly at a given temperature T.
