4blackbody radiation — noun the electromagnetic radiation that would be radiated from an ideal black body; the distribution of energy in the radiated spectrum of a black body depends only on temperature and is determined by Planck s radiation law • Syn: ↑black body… …
5blackbody — noun a hypothetical object capable of absorbing all the electromagnetic radiation falling on it a black body maintained at a constant temperature is a full radiator at that temperature because the radiation reaching and leaving it must be in… …
6blackbody — noun Date: 1710 an ideal body or surface that completely absorbs all radiant energy falling upon it with no reflection and that radiates at all frequencies with a spectral energy distribution dependent on its absolute temperature …
7Color temperature — The CIE 1931 x,y chromaticity space, also showing the chromaticities of black body light sources of various temperatures (Planckian locus), and lines of constant correlated color temperature. Color temperature is a characteristic of visible light …
8Brightness temperature — is the temperature at which a blackbody in thermal equilibrium with its surroundings would have to be in order to duplicate the observed intensity of an object at a frequency u.This is a useful concept only for radiation that obeys the… …
9Thermodynamic temperature — is the absolute measure of temperature and is one of the principal parameters of thermodynamics. Thermodynamic temperature is an “absolute” scale because it is the measure of the fundamental property underlying temperature: its null or zero point …
10Effective temperature — Star The effective temperature of a star is the temperature of a black body with the same luminosity per surface area (mathcal{F} {Bol}) as the star and is defined according to the Stefan–Boltzmann law mathcal{F} {Bol}=sigma T {eff}^4. Notice… …
