h-Bar -- from Eric Weisstein

The black-body problem was revisited in 1905, when Lord Rayleigh and James Jeans (on the one hand) and Albert Einstein (on the other hand) independently proved that classical electromagnetism could never account for the observed spectrum. These proofs are commonly known as the "ultraviolet catastrophe", a name coined by Paul Ehrenfest in 1911. They contributed greatly (along with Ei… Web7 mag 2024 · Le relazioni di De Broglie sono talvolta espresse in termini di costante di Dirac, h-bar= h/ (2 pi), e la frequenza angolare we il numero d'onda k: p= h-bar* kE k = h … La costante di Planck, indicata con , è una costante fisica fondamentale della meccanica quantistica, introdotta come la costante di propozionalità fra l'energia e la frequenza di un fotone nei primi anni del novecento da Max Planck e Albert Einstein nello studio della radiazione emessa da un corpo nero.
