Noun
(physics) the basis of quantum theory; the energy of electromagnetic waves is contained in indivisible quanta that have to be radiated or absorbed as a whole; the magnitude is proportional to frequency where the constant of proportionality is given by Planck's constant
Source: WordNetIf the polylogarithm function and the Riemann zeta function are not available for calculation, there are a number of ways to do this integration; a simple one is given in the appendix of the Planck's law article. Source: Internet
It was an important ingredient for the progressively improved measurements that led to the discovery of Planck's law. Source: Internet
Quantitatively, this can be expressed as Planck's law : ( N·m −2 or Pa ) for a radiation energy density ( J·m −3 ). Source: Internet
The radiation emitted covers the entire electromagnetic spectrum and the intensity of the radiation (power/unit-area) at a given frequency is described by Planck's law of radiation. Source: Internet
This correction is needed because very hot stars radiate mostly ultraviolet radiation, whereas very cool stars radiate mostly infrared radiation (see Planck's law ). Source: Internet
