Question

Quizplus · Accepted Answer

The receptors that detect color are the cones, which are located in the central part of the retina. In very dim light, the rods are primarily responsible for vision, but they do not allow for color perception. Therefore, when Isaac focuses on the faint red light, his cones are not able to detect it properly, and the light appears to disappear.
