The wavelengths of light least absorbed by carotenes are
Correct answer: B. Red to orange
- A. Blue to green
- B. Red to orange
- C. Yellow to orange
- D. Yellow to red
Explanation
Carotenes are pigments that appear red to orange because they reflect these colors of light and do not absorb them efficiently. Instead, they absorb light in the blue-violet spectrum. Therefore, the red to orange wavelengths are least absorbed by carotenes, making Option B correct. Options A, C, and D are incorrect because they either focus on wavelengths that carotenes absorb or misrepresent the range of reflection.
