- Analysing the blackbody spectra of the Sun appears to produce the standard blackbody curve. My understanding off the mechanics behind this is that the electrons in each atom have a discrete number of energy levels and therefore a discrete number of energy level transitions. This would mean that there is a discrete number of wavelengths which could be emitted by the sun, especially since the sun is mainly hydrogen and helium. How is it that the sun's spectra can appear continuous?
My understanding of this is based upon the assumption that energy level transition is the only mechanism responsible for blackbody photons.
