A hypothetical "body" that absorbs all of the electromagnetic radiation striking it - it does not reflect or transmit any of the incident radiation. A blackbody not only absorbs all waveleng [..]

A hypothetical body that cannot be excited to radiate by an external source of electromagnetic radiation of any frequency, direction, or state of polarization except in a negligibly small set of direc [..]

A totally absorbing body that does not reflect radiation. Note: In thermal equilibrium, a blackbody absorbs and radiates at the same rate; the radiation will just equal absorption when thermal equilibrium is maintained.

A theoretical object that radiates the maximum amount of energy at a given temperature, and absorbs all the energy incident upon it. A blackbody is not necessarily black. (The name blackbody was chose [..]

A theoretical body used by the lighting industry as a standard for establishing the "color" and spectral qualities of lamps. A perfect blackbody, when its temperature has risen to 35 [..]

(physics) a theoretical body, approximated by a hole in a hollow black sphere, that absorbs all incident electromagnetic radiation and reflects none; it has a characteristic emission spectrum

(n) a hypothetical object capable of absorbing all the electromagnetic radiation falling on it

(n.) Body capable of absorbing energy of all wavelengths falling on it; it is also capable of radiating all frequencies in a particular ratio to its absorbing properties. The value of the ratio depend [..]

A theoretically perfect absorber of all incident radiation.

An ideal emitter which radiates energy at the maximum possible rate per unit area at each wavelength for any given temperature. A blackbody also absorbs all the radiant energy incident on it; i.e., no [..]

the theoretical "perfect" absorber of light at all wavelengths. As blackbodies heat up, they emit a characteristic double-exponential light frequency (energy) curve, which is imperfectly see [..]

A hypothetical "body" that absorbs all of the electromagnetic radiation striking it - it does not reflect or transmit any of the incident radiation. A blackbody not only absorbs all wavelengths, but emits at all wavelengths with the maximum possible intensity for any given temperature.

A perfect radiator or absorber; a material that absorbs 100% of the radiation striking it and emits the maximum possible radiation at all wavelengths.

A hypothetical "body" that absorbs all of the electromagnetic radiation striking it - it does not reflect or transmit any of the incident radiation. A blackbody not only absorbs all waveleng [..]
