Document Summary
Passing daylight (white light) through prism causes light to refract and you see the rainbow. And if you pass the decompose light back through another prism, you get white light back. Monochromatic light (shades of different colors) can be combined to form other colors. There is no actual color, there is just simply the light hitting object and how you eye analyzes (what type of receptors you have) that stimuli reflecting back. When humans perceive the color of a region their perception is influenced not only by the wavelength of that color, but by the contrast provided by the surrounding region. The opsin that encapsulates 11-cis retinol is slightly different in the three types of cones. Cones see color and are not sensitive to monochromatic light, but are sensitive to a range of colors. Long sensitive cones- most sensitive to yellowish red. Short wavelength- most sensitive to blueish colors i. ii. iii.
