Planck Constant

(h, Planck's Constant)
(quantum of action in quantum mechanics)

The Planck Constant (h) is 6.626068 × 10-34 m2 kg/s. The relation of a photon's energy to frequency is

E = h × f

(E being energy, f being Frequency).

The Reduced Planck Constant (or Dirac Constant, abbreviated ) is h/2π, which is convenient because many equations incorporate this expression.
