Rayleigh-jeans law 유도
WebMar 26, 2016 · The idea of quantized energies arose with one of the earliest challenges to classical physics: the problem of black-body radiation. While Wien’s formula and the Rayleigh-Jeans Law could not explain the spectrum of a black body, Max Planck’s equation solved the problem by assuming that light was discrete.

WebWien's displacement law states that the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature. The shift of that peak is a direct consequence of the Planck radiation law , which describes the spectral brightness or intensity of black-body radiation as a function … WebDas Rayleigh-Jeans-Gesetz beschreibt die Abhängigkeit der spezifischen Ausstrahlung eines Schwarzen Körpers von der Licht wellenlänge , die bei einer gegebenen Temperatur …
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. WebThe ultraviolet catastrophe, also called the Rayleigh-Jeans catastrophe, was the prediction based on classical physics that an ideal black body at thermal equilibrium will emit more energy as the frequency of radiation increases than it was observed in experiments. Studying the laws of black bodies and the failure of classical physics to ...
