In 1900, the British physicist Lord Rayleigh derived the λ dependence of the Rayleigh–Jeans law based on classical physical arguments, relying upon the equipartition theorem. This law predicted an energy output that diverges towards infinity as wavelength approaches zero (as frequency tends to infinity). Measurements of the spectral emission of actual black bodies revealed that the emission agreed with Rayleigh's calculation at low frequencies but diverged at high frequencies; …

WebRayleigh's scattering law. The amount of scattering is inversely proportional to the fourth power of the wavelength. This is known as Rayleigh scattering. As sunlight travels through the earths atmosphere, it gets scattered by the atmospheric particles. Light of shorter wavelengths is scattered much more than light of longer wavelengths. how do i send money to someone on venmoWebBefore the Planck’s hypothesis, physicists tried to describe spectral radiance of electromagnetic radiation by classical physics. The approximation based on classical physics is known as the Rayleigh-Jeans law..
