  2. Wien approximation - Wikipedia

    en.wikipedia.org/wiki/Wien_approximation

    Comparison of Wien’s curve and the Planck curve. Wien's approximation (also sometimes called Wien's law or the Wien distribution law) is a law of physics used to describe the spectrum of thermal radiation (frequently called the blackbody function). This law was first derived by Wilhelm Wien in 1896.

  3. Wien's displacement law - Wikipedia

    en.wikipedia.org/wiki/Wien's_displacement_law

    Formally, the wavelength version of Wien's displacement law states that the spectral radiance of black-body radiation per unit wavelength, peaks at the wavelength given by: = where T is the absolute temperature and b is a constant of proportionality called Wien's displacement constant, equal to 2.897 771 955... × 10 −3 m⋅K, [1] [2] or b ...

  4. Wien's law - Wikipedia

    en.wikipedia.org/wiki/Wien's_law

    Wien's law or Wien law may refer to: . Wien approximation, an equation used to describe the short-wavelength (high frequency) spectrum of thermal radiation; Wien's displacement law, an equation that describes the relationship between the temperature of an object and the peak wavelength or frequency of the emitted light

  5. Wilhelm Wien - Wikipedia

    en.wikipedia.org/wiki/Wilhelm_Wien

    Wilhelm Carl Werner Otto Fritz Franz Wien (German: [ˈvɪlhɛlm ˈviːn] ⓘ; 13 January 1864 – 30 August 1928) was a German physicist who, in 1893, used theories about heat and electromagnetism to deduce Wien's displacement law, which calculates the emission of a blackbody at any temperature from the emission at any one reference temperature.

  6. Black-body radiation - Wikipedia

    en.wikipedia.org/wiki/Black-body_radiation

    A consequence of Wien's displacement law is that the wavelength at which the intensity per unit wavelength of the radiation produced by a black body has a local maximum or peak, , is a function only of the temperature: =, where the constant b, known as Wien's displacement constant, is equal to + 2.897 771 955 × 10 −3 m K. [31]

    For different versions of the law, the proportionality constant differs—so, for a given temperature, there is no unique characteristic wavelength or frequency. The chart plots the peak of the Planck luminosity curve when it is plotted on a per wavelength basis ("peak wavelength"), on a per frequency basis ("peak frequency"), or on a per log ...
