Blackbody formula
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 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 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. 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': where v is the … See more WebMar 14, 2014 · Re units: it's anyway better to always use dimensionless units rather than (arbitrary) SI units. Write the formula on a piece of paper, use substitutions (here, x = \hbar * \omega / k T), express both rhs and lhs in terms of dimensionless functions of dimensionless variables, plot those (and use axis labels for stating the exact variables). –
