Which of the following correctly explains why a green leaf appears green in a bright daylight?

  • I. It absorbs only the green component of sunlight
  • II. It absorbs all colors in sunlight except green
  • III. It reflects only the green component of sunlight

A. I only

B. II and III only

C. I and II only

D. II only.

QUICK ANSWER…

B

DETAILS…

When sunlight falls on a green leaf, the leaf will absorb all other color components of white light except green; that is, the green component will be reflected, this is the reason why the leaf appears green.

Now for the right answer to the above question:

  1. Option A is incorrect. no, it reflects (and not absorbs) only the green component of sunlight.
  2. Option B is correct.
  3. C is incorrect. I is incorrect.
  4. D is not the correct answer. II and III are both correct.

KEY-POINTS…

You may please note these/this:

RELATED!  A mixture of blue and red pigment when...
  • The color in which an object appears under sunlight is simply the color component or components of sunlight, which the object manages to reflect while absorbing others.
  • The different color components of white light are: ROYGBIV = RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, & VIOLET.
  • This also implies a red object manages to appear red because the red component of white light is reflected and others absorbed. very simple!
