WebSep 23, 2024 · where T is the absolute temperature in kelvin and b is a constant of proportionality called Wien's displacement constant, equal to 2.89 × 10 − 3mK, or more conveniently to obtain wavelength in micrometers, b ≈ 2900 μm ⋅ K. This is an inverse relationship between wavelength and temperature. WebThis relationship is called Wien's displacement law and is useful for determining the temperatures of hot radiant objects such as stars, and indeed for a determination of the temperature of any radiant object whose temperature is far above that of its surroundings.. It should be noted that the peak of the radiation curve in the Wien relationship is the peak …
