| Planck's constant |
A universal constant, denoted by h, with the value 6.626075 x 10 -34 Js, in the quantum theory of matter and radiation. Planck's constant is the bridge between the wave and particle descriptions of light, an electromagnetic wave of frequency alternatively described as a stream of photons each with energy h . ...

| Planck's constant |
Planck's constant is a fundamental parameter in quantum mechanics. It determines the size of the discrete units or energy, mass, spin, etc. into which the microscopic world is partitioned. Its value is 1.05 x 10 -27 grams-cm/sec.

| Planck's constant |
h (E=hv where v is the frequency of a radiation, and E is its quantum of energy) and Planck's law of radiation (the magnitude of electromagnetic radiation energy (including light) is the product of Planck's constant and the frequency of the radiation) are named after him. Originator of Quantum theory. [PRS. DoS. RE]

| Planck's constant |
In quantum physics, this is a fundamental constant of nature (h = 1.05 *10 -34 kgms -1 ). It is significant in the subatomic realm, but negligible in macroscopic systems.
