The Wien's displacement law states that the wavelength at which a thermal radiation peak occurs is inversely proportional to the temperature of the source. This means that as the temperature of a source increases, the wavelength at which its peak radiation occurs also increases.
In other words, the Wien's displacement law can be expressed as:
where:
is the wavelength at which the peak radiation is emitted in meters
is the temperature in Kelvin
The Wien's displacement law has several important implications for the study of thermal radiation. First, it provides a way to relate the temperature of a source to the peak wavelength of its radiation. Second, it helps to explain why the spectrum of thermal radiation from a source appears to be shifted towards longer wavelengths as the temperature of the source increases. This is because, according to the law, the peak wavelength of a source's radiation shifts towards longer wavelengths as the temperature increases. Finally, the Wien's displacement law helps to provide a basis for understanding the relationship between temperature, wavelength, and the intensity of thermal radiation
