Question

We cannot distinguish colours in dim light. Explain giving suitable reasons.

Answer 1

Rods are abundantly found in the retina and are sensitive to dim light. Rods also detect changes in the intensity of light across the field of vision and thus aid in the perception of movement. Rods do not play a role in distinguishing colour, and cones are insensitive to dim light. That is why colours can't be seen in dim light.
