  2. 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 ...

    en.wikipedia.org/wiki/Thermal_Remote_sensing

    Stefan–Boltzmann law: Surface temperature of any objects radiate energy and shows specific properties. These properties are calculated by Boltzmann law. 2. Wien's displacement law: Wien's displacement law explains the relation between temperature and the wavelength of radiation. It states that the wavelength of radiation emitted from a ...

  4. 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]

  5. 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.

    Formulas for the various peak wavelengths and mean photon energy were taken from the Wikipedia Wien's displacement law page. The median and quartiles were computed by numerically integrating Planck's law ; however, for any who wish to avoid this, information on percentiles is given in the Planck's law article.

  7. 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

  9. Planck's law - Wikipedia

    en.wikipedia.org/wiki/Planck's_law

    Which peak to use depends on the application. The conventional choice is the wavelength peak at 25.0% given by Wien's displacement law in its weak form. For some purposes the median or 50% point dividing the total radiation into two-halves may be more suitable.
