Answer 1

Give scientific reasons for the following statement.

We cannot distinguish colours in
moonlight.

Answer:

• Retina of the human eye contain photoreceptor cells called rods and cones.
• Colour vision is possible only through
  cones of the retina.
• Cones are stimulated only in bright light while rods are sensitive to dim light.
• Colours like red, violet or purple cannot be distinguished in moonlight because in dim light only the rods function and not the cones.
