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. The net power radiated is the difference between the power emitted and the power absorbed: 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': where v is the … See more • Kroemer, Herbert; Kittel, Charles (1980).
