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.

The lower (blue) curve is total energy according to the Wien approximation, = / The Stefan–Boltzmann law, also known as Stefan's law, describes the intensity of the thermal radiation emitted by matter in terms of that matter's temperature.
12. Sept. 2022 · Figure 6.2.3 6.2. 3: The spectrum of radiation emitted from a quartz surface (blue curve) and the blackbody radiation curve (black curve) at 600 K. Two important laws summarize the experimental findings of blackbody radiation: Wien’s displacement law and Stefan’s law.
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.
22. Juli 2023 · Wien’s Distribution Law, also known as the Wien’s Law or the Wien’s Displacement Equation, is a mathematical expression derived from Wien’s Displacement Law. It provides a quantitative relationship between the peak wavelength of radiation emitted by a black body and its temperature.
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.
