Do we see bands of color in a rainbow because of the physiology of eyes or the way the brain interprets the frequencies? or are those bands of separate colors a product of unequal refraction?
In: Physics
Colors are just different wavelengths of light, within the range that our eyes can detect/process. So objectively, the rainbow is a product of light being split/refracted into many different wavelengths, some of which are in our vision range. But your own experience of color is totally subjective and “do you see the colors in the same way as I do” is a very classic philosophical question, with no answer.
