Question

why does the grass look black under moonlight​

Answer 1

Because the moonlight is very dim and is not enough to illuminate the cells in our retina.

Explanation:

• The grass appears black as there is no sunlight at night.
• At night the moon lights up because of the sunlight falling on its surface and reflecting back.
• Some of the light reflects towards the earth.
• The moonlight is very dim and is not enough to illuminate the cells in our retina.
• Therefore we do not perceive the color of grass undermonnlight and it appears black.
