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.
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:
- Option A is incorrect. no, it reflects (and not absorbs) only the green component of sunlight.
- Option B is correct.
- C is incorrect. I is incorrect.
- D is not the correct answer. II and III are both correct.
You may please note these/this:
- 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!
