Despite the Sun appearing yellow to us on Earth, where does its actual light output peak in the spectrum?
Answer
The green-blue part of the spectrum
Although our Sun is categorized as a yellow star (G-type) and appears yellow or white to observers on Earth, its inherent light output profile is more complex. The peak intensity of the light emitted by the Sun actually occurs within the green-blue portion of the visible spectrum. The reason for the perceived yellow color is attributed to two primary factors: atmospheric scattering occurring in Earth's atmosphere, and the way human eyes integrate the full range of colors received from the star.
