Wien’s Law
According to Wien’s Displacement Law also called Wein’s Law, the black body’s temperature has an inverse relationship with the wavelength with the highest emissive power. The relationship between the peak wavelength (wavelength with peak emissive power, m) and the temperature of the radiating black body is provided by this law.
In other words, this law implies that the hotter objects emit most of their radiation in the shorter wavelength region of the radiation, so they appear blue in color, and colder objects emit most of their radiation in the longer wavelength spectrum of the radiation, hence they appear redder in color.
Wien’s Displacement Law
Wein’s Displacement Law or Wein’s Law is named after the man who discovered it, Wilhelm Wien; a German physicist. Wilhelm Wein has done remarkable work in the field of Radiation, for which he was granted a noble price for physics in 1911. Max Planck who was a colleague of Wien, continued his work on the same topic and gave Wein-Plank Law and further a more general law Planck’s Law of Radiation. Wein’s Displacement Law is a fundamental concept in the study of radiation and describes the relationship between the temperature of an object and the wavelength of its maximum emission of radiation. This short article provides a thorough explanation of Wein’s law, including the mathematical formulation and various ways it can be expressed.
