KnowraWien approximationLinked fromLinked fromThe 7 pages that link to Wien approximation, each with the reason it gives.All 7Broader topic 2Compared with 5Planck's lawBroader topic: It simplifies Planck's law in the high-frequency, low-occupation regime.Ultraviolet catastropheCompared with: It avoids the ultraviolet divergence but fails to describe the low-frequency spectrum.Rayleigh–Jeans lawCompared with: It describes the short-wavelength regime opposite the Rayleigh–Jeans law’s domain of accuracy.Wien's displacement lawCompared with: This related result approximates spectral intensity, whereas displacement law locates its peak.Wilhelm WienBroader topic: Wien proposed this formula before Planck derived a distribution valid across the full spectrum.Photon gasCompared with: It approximates the photon gas spectrum only in the short-wavelength tail.Stefan–Boltzmann constantCompared with: It describes one spectral region rather than the integrated flux fixed by σ.
