Sun blackbody temperature
A black body at room temperature (23 °C (296 K; 73 °F)) radiates mostly in the infrared spectrum, which cannot be perceived by the human eye, but can be sensed by some reptiles. As the object increases in temperature to about 500 °C (773 K; 932 °F), the emission spectrum gets stronger and extends into the … 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 the wave is observed to have frequency f': where v is the … See more Spectrum Black-body radiation has a characteristic, continuous frequency spectrum that depends only on the … See more Human-body emission The human body radiates energy as infrared light.
