• ## Planck constant - Wikipedia

en.wikipedia.org/wiki/Reduced_Planck_constant The Planck constant, or Planck's constant is the quantum of electromagnetic action that relates a photon's energy to its frequency. The Planck constant multiplied by a photon's frequency is equal to a photon's energy. The Planck constant is a fundamental physical constant denoted as , and of fundamental importance in quantum mechanics.In metrology it is used to define the kilogram in SI units.
