WebSep 11, 2015 · Methods by which the correlated color temperature and the distribution temperature of a light source may be calculated from a knowledge of the spectral power distribution of the source are described. When a black body is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. Its emission is called black-body radiation. The concept of the black body is an idealization, as perfect black bodies do not exist in nature. 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 $${\displaystyle B_{\nu }(T)={\frac {2\nu ^{2}}{c^{2}}}{\frac {h\nu }{e^{h\nu /kT}-1}},}$$ where 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 … 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 peaked at a characteristic frequency that … See more Human-body emission The human body radiates energy as infrared light.
