1. Your graph should have two "peaks." At the highest of the two, what wavelength was most
strongly absorbed by the chloroplast pigments?
What wavelength corresponds the top of the second peak?
What wavelength was least absorbed by the chloroplast pigments?
2. Based on your observations, which wavelength (color) of light might be expected to generate the
lowest rate of photosynthesis?
