WebA black body is an idealized model of a physical object that absorbs all incident electromagnetic radiation. Because it is a perfect absorber at all wavelengths, a black body is also an ideal emitter of thermal radiation. This black body radiation has a certain frequency (or wavelength) distribution, which is characterized by a maximum. Web2 Mar 2015 · The spectrum of sunlight has approximately the spectrum of a black-body radiating at about 6,000 K, interspersed with atomic absorption lines from the tenuous …
Why is the Sun approximated as a black body at ~ 5800 K?
WebA black body is one that absorbs all the EM radiation (light...) that strikes it. To stay in thermal equilibrium, it must emit radiation at the same rate as it absorbs it so a black body also radiates well. (Stoves are black.) … Web21 Mar 2024 · The solar surface can be considered as a first approximation as a black surface; the density ρ λ (λ,T) of the solar radiation is maximum for λ m = 0.501 µm. From Wien’s law it is then possible to deduce the temperature of the solar surface T S = 5777 K. – Heat flux radiated by the Sun to the Earth. gray metal folding chairs with cushion
