AP PSYCHOLOGY

Detailed explanation-1: -The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are not good for color vision. In a dim room, however, we use mainly our rods, but we are “color blind.” Rods are more numerous than cones in the periphery of the retina.

Detailed explanation-2: -Cone Details They provide the eye’s color sensitivity. The green and red cones are concentrated in the fovea centralis . The “blue” cones have the highest sensitivity and are mostly found outside the fovea, leading to some distinctions in the eye’s blue perception.

Detailed explanation-3: -1. Rods are the cells which are sensitive to the bright light and colour. 2. Cons are the cells which are sensitive to the dim light.

Detailed explanation-4: -Rods and cones are the light-sensitive cells on the retina. Cones are sensitive to bright light and are capable of colour vision. Rods are sensitive to dim light and give twilight vision. They convert light waves into electrical impulses which are read by the brain.

Detailed explanation-5: -Rods are usually found concentrated at the outer edges of the retina and are used in peripheral vision. On average, there are approximately 92 million rod cells (vs  6 million cones) in the human retina. Rod cells are more sensitive than cone cells and are almost entirely responsible for night vision.
