Question

What was the contribution of the black body Paradox in the discovery of 1920s? Why did Wien's Law only work on high frequencies?
$wiens \: law \: = u{(v.t)} = av {}^{5} e {}^{ \beta t \div kt}$
​

Answer 1

Wien's approximation (also sometimes called Wien's law or the Wien distribution law) is a law of physics used to describe the spectrum of thermal radiation (frequently called the blackbody function). This law was first derived by Wilhelm Wien in 1896.[1][2][3] The equation does accurately describe the short wavelength (high frequency) spectrum of thermal emission from objects, but it fails to accurately fit the experimental data for long wavelengths (low frequency) emission.
