what spectrum of light does chlorophyll use
Absorption spectrum of chlorophyll a and chlorophyll b. The use of both together enhances the size of the absorption of light for producing energy. Chlorophyll a absorbs light within the violet, blue and red wavelengths while mainly reflecting green. This reflectance gives chlorophyll its green appearance. Accessory photosynthetic pigments broaden the spectrum of light absorbed, increasing the range of wavelengths that can be used in photosynthesis. The addition of chlorophyll b next to chlorophyll a extends the absorption spectrum.
