PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Rods don’t help with color vision, which is why at night, we see everything in a gray scale. The human eye has over 100 million rod cells. Cones require a lot more light and they are used to see color. We have three types of cones: blue, green, and red.

Detailed explanation-2: -Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity. Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones.

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: -The cone cells are of three types: Red (R), Green (G) and Blue (B) cells. Each type of cone cell responds to a range of wavelengths, with a particular wavelength showing the maximum response.

Detailed explanation-5: -Different rods and cones react to different wavelengths, or colors, of light. When light hits the rods and cones, they send electrical signals to let the brain know. They do that through the optic nerve. Like roads and highways, nerves carry signals around the brain and body.
