In the retina detect light to generate images
WebBecause light rays diverge in all directions from their source, the set of rays from each point in space that reach the pupil must be focused. The formation of focused images on the … WebAfter Images. Color is light and colored objects absorb and reflect different wavelengths. Light & color are seen by the human eye because of the two types of photoreceptor cells - rods and cones - located in the retina of the eye. Rods are sensitive to light and dark; cones are sensitive to red, green & blue light and responsible for color vision.
