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 ...
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.

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
Wilhelm Carl Werner Otto Fritz Franz Wien (German: [ˈvɪlhɛlm ˈviːn] ⓘ; 13 January 1864 – 30 August 1928) was a German physicist who 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.
The film industry in Albania comprises the art of films and movies made within the country or by Albanian directors abroad. Albania has had an active cinema industry since 1897 and began strong activities in 1940 after the foundation of both the "Kinostudio Shqipëria e Re" and National Center of Cinematography in Tirana.

It Is the Law is a 1924 American silent mystery film directed by J. Gordon Edwards and starring Arthur Hohl, Herbert Heyes, and Mona Palma. It is a film adaptation of the 1922 Broadway play of the same name by Elmer Rice, itself based on a novel by Hayden Talbot. The film depicts the story of Ruth Allen (Palma), who marries Justin Victor (Heyes ...
