Wien's Displacement Law states that the wavelength at which the emission of radiation from a black body is maximized is inversely proportional to its absolute temperature. This means that as the temperature of an object increases, the peak wavelength of the emitted radiation shifts to shorter wavelengths. For example, a hotter object like a star emits most of its radiation at shorter wavelengths, such as visible light or ultraviolet radiation, while a cooler object, like a red-hot metal, emits radiation at longer wavelengths, such as infrared radiation. This law helps explain why hotter objects appear brighter and bluer than cooler ones.
