WebIn 1900, Max Planck developed the modern theory describing the radiation field of a blackbody. At the time, there were two distinct models for blackbody radiation: the Rayleigh-Jeans law, which fit the measurements well at low frequencies, and Wien’s law, which worked well at high frequencies, but neither worked everywhere. WebJan 1, 2015 · I don't understand the conversion between the frequency and wavelength forms of the Rayleigh-Jeans equation for spectral radiance. According to the Wikipedia …

WebQuantitatively, Wien’s law reads. λ max T = 2.898 × 10 −3 m · K. 6.1. where λ max is the position of the maximum in the radiation curve. In other words, λ max is the wavelength at which a blackbody radiates most strongly at a given temperature T. Note that in Equation 6.1, the temperature is in kelvins.
