Formula planck constant
The Planck constant, or Planck's constant, is a fundamental physical constant of foundational importance in quantum mechanics. The constant gives the relationship between the energy of a photon and its frequency, and by the mass-energy equivalence, the relationship between mass and frequency. … See more Planck's constant was formulated as part of Max Planck's successful effort to produce a mathematical expression that accurately predicted the observed spectral distribution of thermal radiation from a closed furnace ( See more 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 … See more The Planck constant has dimensions of angular momentum. In SI units, the Planck constant is expressed with the unit joule per hertz (J⋅Hz ) or joule-second (J⋅s). $${\displaystyle h=\mathrm {6.626\ 070\ 15\times 10^{-34}\ J{\cdot }Hz^{-1}} }$$ The above values … See more • Electronics portal • Chemistry portal • CODATA 2024 • International System of Units See more The Planck relation connects the particular photon energy E with its associated wave frequency f: $${\displaystyle E=hf.}$$ This energy is … See more Implicit in the dimensions of the Planck constant is the fact that the SI unit of frequency, the hertz, represents one cycle per second.
