WebSuppose that light from the yellow region of the spectrum, with a wavelength of say 580 nm, arrives at the retina. It lies between that of red (say 620 nm) and green (550 nm), so this light stimulates both red and green photoreceptors. This … WebIn Earth's atmosphere, the dominant scattering efficiency of blue light is compared to red or green light. Scattering and absorption are major causes of the attenuation of sunlight radiation by the atmosphere.
