How does a green leaf appear in the red light? Use what you know about reflection and absorption of light.

A. black

B. Green

C. Greenish-red

D. Red

E. White

black, all the colors have been absorbed

We call it a "green" leaf because green light bounces off of it and enters our eyes. Other colors of light are absorbed by the leaf and stop right there.

If there's no green light to bounce off of the leaf, then no light at all comes from it.

When we look at an object that has no light coming from it, we describe the object as "black". We only know it's there because of its background and surroundings.
