Planck was able to calculate the value of from experimental data on black-body radiation: his result, 6.55 × 10 −34 J⋅s, is within 1.2% of the currently defined value. He also made the first determination of the Boltzmann constant k B {\displaystyle k_{\text{B}}} from the same data and theory. See more 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 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 … 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. One cycle corresponds to 2π radians of phase angle. In applications where it is natural to use the See more In principle, the Planck constant can be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, … 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 … See more The Planck relation connects the particular photon energy E with its associated wave frequency f: $${\displaystyle E=hf.}$$ This energy is extremely small in terms of ordinarily perceived everyday objects. Since the frequency f, 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).
