What do rods detect?

Only colors

Fine details

Black, white, and gray

Rods are photoreceptor cells located in the retina of the eye, specifically designed to be highly sensitive to light. They play a crucial role in our vision, particularly in low-light conditions. Unlike cones, which are responsible for detecting colors and provide sharp details in bright light, rods do not have the capacity to perceive color. Instead, they are adept at detecting varying levels of light and are primarily responsible for night vision. As a result, rods are most sensitive to shades of black, white, and gray, allowing us to see in dimly lit environments. This characteristic makes the option describing their ability to detect black, white, and gray the correct choice.
