Inset image (A) has the raw data values, which range from 9070 to 21284. Inset image (B) shows the same image converted to spectral radiance, where values … For a black body (a perfect absorber) there is no reflected radiation, and so the spectral radiance is entirely due to emission. In addition, a black body is a diffuse emitter (its emission is independent of direction). Consequently, black-body radiation may be viewed as the radiation from a black body at thermal … 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 Human-body emission The human body radiates energy as infrared light. The net power radiated is the difference between the power emitted and the power absorbed: Applying the … 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 Spectrum Black-body radiation has a characteristic, continuous frequency spectrum that depends only on … 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 See more • Bolometer • Color temperature • Infrared thermometer • Photon polarization See more
