Wien’s Law What is it? Wien’s Law tells us where (meaning at what wavelength) the star's brightness is at a maximum. See the picture below – the red dot under the word “visible” is the peak for the 6000 K object. In other words, Wien's law tells us what color the object is brightest at.
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. [1] [2] [3] The equation does accurately describe the short- wavelength (high- frequency ...

빈 변위 법칙. 다양한 (절대) 온도에 대한 파장 함수로서의 흑체 열 방출 강도. 통계역학 에서 빈 변위 법칙 (Wien變位法則, Wien's displacement law )은 특정 온도에서 흑체 로부터 방사된 열 에너지의 파장 분포가 필수적으로 다른 온도의 분포와 같은 모양을 가진다는 ...
b is a constant of proportionality, called Wien's displacement constant and equals 2.897 768 5(51) × 10 –3 m K (2002 CODATA recommended value) The two digits between the parentheses denotes the uncertainty (the standard deviation at 68.27% confidence level) in the two least significant digits of the mantissa.
Wien’s Law, named after the German Physicist Wilhelm Wien, tells us that objects of different temperatures emit spectra that peak at different wavelengths. Hotter objects emit radiations of shorter wavelengths, and hence they appear blue. Similarly, cooler objects emit radiations of longer wavelengths, and hence they appear reddish.
Wilhelm Wien. Wilhelm Carl Werner Otto Fritz Franz Wien ( German pronunciation: [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 ...
