WebDec 7, 2002 · The Rayleigh-Jeans Law was a proposed solution to the problem of blackbody radiation, first proposed by Lord Rayleigh in 1900 and corrected slightly by James Jeans shortly thereafter. Like Wien's Law, the Rayleigh-Jeans Law relies on classical physics, though Rayleigh used statistical mechanics to study standing waves in a cavity rather … WebSep 22, 2016 · This problem says I need to find the low-frequency limit (which will lead to the Rayleigh-Jeans), and I need to take the high-frequency limit, which is supposed to lead to Wien's distribution. The thing is I have no idea what the high, or low frequency limit even means, I've looked in my book, I've looked online, I'm not sure exactly what it means.
