Term information
The Planck constant (denoted h), also called Planck's constant, is a physical constant reflecting the sizes of quanta in quantum mechanics. It is named after Max Planck, one of the founders of quantum theory. The Planck constant was first described as the proportionality constant between the energy (E) of a photon and the frequency of its associated electromagnetic wave (Einstein equation: E = h\nu.\, Since the frequency = c, the Planck relation can also be expressed as E = \frac{hc}{\lambda}.\, source: http://en.wikipedia.org/wiki/Planck%E2%80%93Einstein_equation
