WHAT DOES DIRAC CONSTANT MEAN IN ENGLISH?

Dirac constant

Planck constant

The Planck constant is a physical constant that is the quantum of action in quantum mechanics. Published in 1900, it originally described the proportionality constant between the energy of a charged atomic oscillator in the wall of a black body, and the frequency of its associated electromagnetic wave. Its relevance is now integral to the field of quantum mechanics, describing the relationship between energy and frequency, commonly known as the Planck relation: In 1905 the value, the energy of a charged atomic oscillator, was theoretically associated with the energy of the electromagnetic wave itself, representing the minimum amount of energy required to form an electromagnetic field. Further investigation of quanta revealed behaviour associated with an independent unit as opposed to an electromagnetic wave and was eventually given the term photon. The Planck relation now describes the energy of each photon in terms of the photon's frequency. This energy is extremely small in terms of ordinary experience.
