At high frequencies this law is replaced by Wien's formula, while at high wavelengths the Rayleigh-Jeans formula applies.
At high frequencies this law is replaced by Wien's formula, while at high wavelengths the Rayleigh-Jeans formula applies. It states that for the wavelength interval lambda to lambda plus delta lambda, the formula 4 pi times I sub lambda divided by c gives the energy radiated per unit volume by a cavity of a blackbidy. FTP, what is this revolutionary 1900 law which first introduced the idea that energy is radiated in quanta?
