Solar blackbody curve
WebWien's Displacement Law. For a blackbody radiator, the temperature can be found from the wavelength at which the radiation curve peaks. Discussion. If the temperature is = C = K, then the wavelength at which the radiation curve peaks is: λ peak = x10^ m = nm = microns. This wavelength corresponds to quantum energy. hν = x 10^ eV.

WebMay 5, 2011 · The light coming from the photosphere (the "surface" of the sun) is approximately a black body but the atoms/ions in the thinner outer layers of the sun (ie. the chromosphere) absorb and re-emit certain wavelengths of light. That's what gives us the sun's absorption lines in its spectrum and causes it to not be a perfect black body. May 5, …
WebSep 7, 2010 · The blackbody is the best possible absorber and emitter of radiant energy at any wavelength and in any direction. The total (including all wavelengths) radiant intensity and hemispherical total emissive power of a blackbody into a medium with constant index of refraction n are given by the Stefan-Boltzmann law, π I b = E b = n 2 σ T 4. Webpresent in the extraterrestrial solar spectrum; (2) a smoothly varying trend toward lower intensity at increasing wavelengths; this arises from a combination of three factors: (i) the variation of solar intensity with wavelength, which closely follows a blackbody curve at 5800 K, peaking at about
