An object which absorbs all the radiation which falls on it, and is, therefore perfectly black.
A body or material that absorbs 100% of the energy incident upon it. Blown Fiber — A method for installing fiber in which fibers are blown through a vessel, such as a tube.
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 equilibrium"
a conceptual object in physics that absorbs all radiation
a hypothetical cosmic body that absorbs all radiation falling on it, but reflects none what-so-ever
an ideal emitter which is capable of absorbing and emitting all frequencies of radiation uniformly
an ideal emitter which radiates energy at the maximum possible rate per unit area at each wavelength for anygiven temperature
an ideal incandescent light source, with an emission spectrum that does not depend on what material the light comes from, but only its temperature
an idealised object which radiates heat energy according to a certain simple physical model
an ideal object that absorbs all light incident upon it
an imaginary body that absorbs all the thermal radiation onto it and is a perfect emitter of thermal radiation as a continuous spectrum, i
an object that absorbs all radiant energy that hits it
an object which absorbs all incident light and thus is black in appearance
a notional heated box that emits electromagnetic radiation (light, and its cousins such as radio and X-rays) at all frequencies
a specially prepared perfect thermal radiator with a light spectrum that depends only on temperature
a surface that absorbs all radiation of any wavelength falling on it
a theoretically perfect absorber and emitter of radiation
a theoretically perfect radiator
a theoretical perfect absorber, which absorbs radiation of all wavelengths falling on it
a theoretical perfect radiator
a theoretical radiator and absorber of energy at all electromagnetic wavelengths
A body, unit, surface or element that absorbs all the radiation that falls upon it.
A body that absorbs all wavelengths of electromagnetic radiation. Conversely, when heated a black body emits in all wavelengths.
A theoretical ideal emitter of electromagnetic radiation
A hypothetical, ideal body which absorbs completely all incident radiation, independent of wavelength and direction. No actual substance behaves as a true black body, although platinum black and other soots rather closely approximate this ideal. However, one does speak of a black body with respect to a particular wavelength interval. Compare to gray body, white body.
A black body is an idealized body that is a perfect radiator and perfect absorber of electromagnetic radiation. A black body not only absorbs all wavelengths of energy and radiates at all wavelengths, but it does this at the maximum possible intensity for any given temperature. It doesn't necessarily look black. A star is a good approximation to a black body since stellar gases are very good absorbers of energy.
A theoretical object that is both a perfect absorber and emitter of radiation. A star approximates closely to this ideal. The distribution of energy (as a function of wavelength) from a blackbody depends only on the temperature of the object.
Theoretical object absorbing the totality of incidental radiations. So the light emitted since a black body comes only from him and was not considered.
A perfect absorber and radiator of energy, and an object whose spectrum is totally dependent on its temperature. Colder black bodies appear red, and hotter black bodies appear blue, or white. Stars closely mimic blackbodies; cool stars are red while hot stars are blue or white.
a hypothetical body able to absorb all the radiation it receives without emitting any, and therefore it appears completely black. However, if the black body is heated, a radiation emission occurs, with a maximum of intensity at a wavelength which is lower, as the temperature reaches higher levels. Therefore, in Astrophysics, the radiation emitted by a star can be also described by the black body temperature; that is the temperature of a black body which emits a radiation with the same wavelength distribution as the star.
A body, which completely absorbs any heat or light radiation falling upon it.
Is a body that emits electromagnetic radiation, at any temperature, at the maximum possible rate per unit surface area. This body also absorbs all electromagnetic radiation that is intercepted by it.
A perfect absorber and radiator of energy. Its spectrum is totally dependent on the temperature of the black body; cold black bodies appear red, hot black bodies appear blue, or white. Stars actually mimic blackbodies closely...cool stars are red while hot stars are blue or white.
A body that absorbs all the radiation that it receives, giving it an albedo of zero i.e. it is 100% efficient at absorbing radiation. A black body also radiates with 100% efficiency, it is therefore a theoretical object although many stars come very close to this theoretical position.
In physics, a black body is an object that absorbs all electromagnetic radiation that falls onto it. No radiation passes through it and none is reflected, yet in classical physics, it can theoretically radiate any possible wavelength of energy. Despite the name, black bodies are not actually black as they radiate energy as well.
