Wilhelm Wien 1865-1928 "grew up in the east Prussian town of Rastenburg today Ketrzyn Lithuania. He then studied at the prominent universities of Heidelberg and Göttingen before he eventually completed his doctorate in Berlin. In 1900 he succeeded W.C. Röntgen 1901 Physics Laureate as a professor in Würzburg. Wien's research concerned how various metals radiate heat and he received the Nobel Prize for the law of black-body radiation now known as Wien-Planck's law. It was drawn up jointly with Max Planck Physics 1918 and many felt that they should have shared in the award." "When a completely dark body is heated it emits visible light and other electromagnetic radiation. The spectrum of the radiation is entirely dependent on the temperature of the body and not its composition. In 1893 Wilhelm Wien formulated his displacement law which indicates at which wavelength the radiation is most intense at a certain temperature. He subsequently also formulated a law indicating how the radiation spectrum varies as temperature changes. However this does not apply to long wavelengths and in 1900 Max Planck formulated a law that conforms better." Wilhelm Wien - Facts. NobelPrize/org The Nobel Prize in Physics 1911 unknown
