Planck's constant. A physical constant that is used extensively in quantum mechanics and fixes the scale of quantization of many phenomena, such as the relation between the energy of a photon (a quantum of light) and its wavelength. Its value is approximately 6.626 Ã 10-34 joule-seconds (equivalent to units of angular momentum).
