Question

Why are leaves green?

a. chlorophyll molecules mainly absorb light in the ultraviolet and red-orange part of the electromagnetic spectrum. chlorophyll does not absorb much green light, which is reflected to our eyes.

b. chlorophyll molecules mainly absorb light in the blue-violet and red-orange part of the electromagnetic spectrum. chlorophyll does not absorb much green light, which is reflected to our eyes.

c. chlorophyll molecules mainly absorb light in the ultraviolet and infrared part of the electromagnetic spectrum. chlorophyll does not absorb much green light, which is reflected to our eyes.

d. chlorophyll molecules mainly absorb light in the blue-violet and infrared part of the electromagnetic spectrum. chlorophyll does not absorb much green light, which is reflected to our eyes.

e. chlorophyll molecules mainly absorb light in the green part of the electromagnetic spectrum?

Answer 1

The answer is B) The chlorophyll absorbs the red and blue light, and reflects the green light into our eyes, making it appear green. This is because red wavelengths are very long waves, and blue waves are very short length waves. However, the green waves are medium sized, and the chlorophyll has trouble absorbing it at that wavelength.
