WebA black body is an idealized body that fully absorbs impinging electromagnetic radiation of any wavelength. Neither reflection nor transmission occur on it. A black body radiates at every wavelength the maximum possible energy for all possible emitters. The radiation density is independent of angles here. The black body forms the basis for ... WebMar 3, 2024 · blackbody, also spelled black body, in physics, a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black. The concept of such a perfect absorber of energy is extremely useful in the study of radiation phenomena, as in …

WebThe reflectivity of a blackbody is always zero. The monochromatic absorptivity of a real body surface is less than 1 for external irradiation, thus its reflection ratio is not zero relative to direction and wavelength.
