In physics, the Rayleigh–Jeans Law, first proposed in the early 20th century, attempts to describe the spectral radiance of electromagnetic radiation at all wavelengths from a black body at a given temperature through classical arguments. For wavelength , it is; where c is the speed of light, k is Boltzmann's constant and T is the temperature in kelvins. For frequency , it is; .

  • In physics, the Rayleigh–Jeans Law, first proposed in the early 20th century, attempts to describe the spectral radiance of electromagnetic radiation at all wavelengths from a black body at a given temperature through classical arguments. For wavelength , it is; where c is the speed of light, k is Boltzmann's constant and T is the temperature in kelvins. For frequency , it is; . The Rayleigh–Jeans expression agrees with experimental results at large wavelengths (or, equivalently, low frequencies) but strongly disagrees at short wavelengths (or high frequencies). This inconsistency is commonly known as the ultraviolet catastrophe.
