AP PSYCHOLOGY

Detailed explanation-1: -Cones require a lot more light and they are used to see color. We have three types of cones: blue, green, and red. The human eye only has about 6 million cones. Many of these are packed into the fovea, a small pit in the back of the eye that helps with the sharpness or detail of images.

Detailed explanation-2: -Scientists have known for decades that some cells-known as cones-detect color. They are part of the retina inside the back of the eye. Cone cells can sense red, green or blue light.

Detailed explanation-3: -There are 2 types of photoreceptors: rods, which detect dim light and are used for night vision, and cones, which detect different colors and require brightly lit environments. Humans have 3 distinct color-sensing cones-for red, green, and blue light.

Detailed explanation-4: -Signals from the cones are sent to the brain which then translates these messages into the perception of color. Cones, however, work only in bright light. That’s why you cannot see color very well in dark places. So, the cones are used for color vision and are better suited for detecting fine details.

Detailed explanation-5: -Cones contain photo pigments, or color-detecting molecules. Humans typically have three types of photo pigments-red, green and blue. Each type of cone is sensitive to different wavelengths of visible light. In the daytime, a lemon’s reflected light activates both red and green cones.
