Web10 Aug 2014 · The spectrum of the Sun is very close to that of a 5778 K black body, but there are deviations. Some are due to absorption and emission, but others result from … WebStars approximate blackbody radiators and their visible color depends upon the temperature of the radiator. The curves show blue, white, and red stars. The white star is adjusted to 5270K so that the peak of its blackbody curve is at the peak wavelength of the sun, 550 nm.

Web9 Apr 2015 · I’ve read that the light we can see coming from the sun originates from the suns photosphere which can be modeled as a black body emitter with a temperature of 5760 K. If I use Wien’s displacement law with this temperature to find out where the peak wavelength is: Peak = (2.8977*10^-3)/5760 = 503 nm WebThe radiation emitted by the Sun is significant amount while passing through the visible light spectrum. The sun’s radiation is measured as 50nm. Is there evidence of the sun producing harmful ultraviolet radiation? Explain. The harmful ultraviolet radiation emits from 100 to 400 nm wavelength. So yes, this explains that Sun is producing uv rays. WebBlackbody Curve and Wien's Law Explained (UPDATED) - YouTube This is the UPDATED version of my video on Wien's Law.
