Rayleigh-jeans approximation
WebRayleigh-Jeans Law. A classical law approximately describing the intensity of radiation emitted by a blackbody, derived by Rayleigh and Jeans by counting the number of standing wave modes in an enclosure. It corresponds to the Planck law in the case of small frequencies, in which case allows the approximation. (1) WebThe Rayleigh scheme for counting modes. We need to evaluate the number of modes which can meet this condition, which amounts to counting all the possible combinations of the …
