Quizplus · Accepted Answer

Chlorophyll a has a peak absorption at 660 nm and chlorophyll b has a peak absorption at 640 nm, meaning they both have peaks of absorption at different wavelengths. Chlorophyll also absorbs light in the range of 400-700 nm, but it does not absorb green light, which is why leaves appear green to our eyes. The maximum absorption for chlorophyll a is actually around 680 nm.
