WebThe law is derived from classical physics arguments. Lord Rayleigh first obtained the fourth-power dependence on wavelength in 1900; a more complete derivation, which included the proportionality constant, was presented by Rayleigh and Sir James Jeans in 1905. It agrees with experimental measurements for long wavelengths. WebAccording to Rayleigh Jeans radiation waves in black body can be compared to the standing waves in cubical cavity. Let the equation of standing wave is y Akr tAkxkykz tsin . cos sin cos xy z where ˆˆˆ kkikjkk x yz is wave vector. For standing wave at the wall their must be only nodes so x ,,y z xy z
WebRayleigh-jeans law: A black body in thermal equilibrium will emit radiation in all frequency ranges, and as the frequency increases, so does the energy of the radiation emission. The black body is a matter that can absorb and emit all energy that comes into contact with it. The greater the intensity, the higher the temperature of the matter.
