The name "black body" is given because it absorbs all colors … WebMar 30, 2016 · For a real body, the amount of energy absorbed depends on frequency of the radiation and temperature of the reflecting body. So for a real object, the above reasoning is not really applicable. The power absorbed when the body is cold will be different than the power absorbed when it is in equilibrium with the large sphere.

A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The name "black body" is given because it absorbs all colors of light. A black body also emits black-body radiation. In contrast, a white body is one with a "rough surface that reflects all incident rays completely and uniformly in all directions."

Black-body radiation is the thermal electromagnetic radiation within, or surrounding, a body in thermodynamic equilibrium with its environment, emitted by a black body (an idealized opaque, non-reflective body). It has a specific, continuous spectrum of wavelengths, inversely related to … See more Spectrum Black-body radiation has a characteristic, continuous frequency spectrum that depends only on the body's temperature, called the Planck spectrum or Planck's law. The spectrum is … See more Human-body emission The human body radiates energy as infrared light.
