In physics, Wien's displacement law states that the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature.

Wien's displacement law in its stronger form states that the shape of Planck's law is independent of temperature. It is therefore possible to list the percentile points of the total radiation as well as the peaks for wavelength and frequency, in a form which gives the wavelength λ when divided by temperature T .

Wien’s displacement law allows us to estimate the temperatures of distant stars by measuring the wavelength of radiation they emit. Example \(\PageIndex{1}\): Temperatures of Distant Stars On a clear evening during the winter months, if you happen to be in the Northern Hemisphere and look up at the sky, you can see the constellation Orion ...
a result known as the Wien displacement law. The constant of proportionality is the Wien displacement constant \(b \approx 2900 \, \mu\text{m} \cdot \text{K} \). In general, as a blackbody heats up, its emission spectrum shifts to a high-energy spectrum, represented by emission at a shorter wavelength or, equivalently, higher frequency.
31. Juli 2013 · Wien’s displacement law has an important part in the development of modern quantum theory, and predicting it was one of the triumphs of Planck’s distribution law. It is usually expressed in terms of wavelength. Less known, however, is its expression in terms of frequency.
13. Jan. 2023 · Wien’s Displacement Law. In the years of 1893/94, Wien developed his displacement law and from 1894 to 1896, he developed his radiation law to describe the thermal radiation emitted by a blackbody as a function of wavelength. In particular, Wien’s displacement law states that the wavelength at which a blackbody of absolute ...
