Blackbody assumption
Did you know?
In the laboratory, black-body radiation is approximated by the radiation from a small hole in a large cavity, a hohlraum, in an entirely opaque body that is only partly reflective, that is maintained at a constant temperature. (This technique leads to the alternative term cavity radiation .) See more 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 … See more Planck's law of black-body radiation Planck's law states that $${\displaystyle B_{\nu }(T)={\frac {2\nu ^{2}}{c^{2}}}{\frac {h\nu }{e^{h\nu /kT}-1}},}$$ See more In his first memoir, Augustin-Jean Fresnel (1788–1827) responded to a view he extracted from a French translation of Isaac Newton's Optics. He says that Newton imagined … See more • Bolometer • Color temperature • Infrared thermometer • Photon polarization See more Spectrum Black-body radiation has a characteristic, continuous frequency spectrum that depends only on … See more Human-body emission The human body radiates energy as infrared light. The net power radiated is the difference between … See more The relativistic Doppler effect causes a shift in the frequency f of light originating from a source that is moving in relation to the observer, so that the wave is observed to have frequency f': See more 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."

If it were not so, that is, the temperature of the body was different from its surroundings, then in a net exchange with its surroundings, the body will radiate/absorb heat energy from its surrounding ...
