Question

What wavelengths of light does chlorophyll absorb best?

a. 662 nm and 700 nm
b. 500 nm and 600 nm
c. 400 nm and 430 nm
d. 430 nm and 662 nm

Answer 1

d. 430 nm and 662 nm.

Step-by-step explanation:

Answer 2

d. 430 nm and 662 nm. Both Chlorophyll a and Chlorophyll b can best absorb light at the 450 nm to 650 nm spectrum. Violet blue wavelength is available at 450 nm and red at 650 nm. Chlorophylls are unable to absorb green, yellow and orange parts of the spectrum.
