Wien's law
Encyclopedia
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 lawWien's displacement lawWien's displacement law states that the wavelength distribution of thermal radiation from a black body at any temperature has essentially the same shape as the distribution at any other temperature, except that each wavelength is displaced on the graph...
, an equation that describes the relationship between the temperature of an object and the peak wavelength or frequency of the emitted light. - Wien-Planck law, an alternate name for the Planck law, which describes the complete spectrum of thermal radiation.
