WebBoltzmann law, being a limiting case of Planck’s law of radiation. Undergraduate physics courses almost invariably present Planck’s Law, without much discussion, if any, as to how he arrived at it. They leave that to the historians of physics and the de nitive explanation of that process is probably given by Max Jammer in [1] (pages 1-21 ... WebAfter this, he was joined by Sir James Jeans in the year 1905. Initially, Lord Rayleigh claimed the λ depends on the Rayleigh - Jeans law. That was concluded on the basis of arguments made by classical physicists and various empirical facts. This law was explained more clearly in the year 1905 by both Lord Rayleigh and Sir James Jeans.
