Wilhelm Wien

Wilhelm Wien was a German physicist who made important contributions to understanding how objects emit and absorb energy through radiation. He is best known for Wien's Displacement Law, which describes how the peak wavelength of blackbody radiation shifts with temperature—meaning hotter objects emit light at shorter wavelengths. This discovery helped pave the way for the development of quantum theory and our understanding of thermal radiation. Wien's work provided foundational insights into how energy is transferred as heat and light, influencing fields like astrophysics, thermodynamics, and quantum mechanics.
