Question: what is the general relationship between light absorbance and photosynthetic activity?
Answer: Pigments absorb light used in photosynthesis. In photosynthesis, the sun's energy is converted to chemical energy by photosynthetic organisms. ... The absorption spectrum of chlorophylls includes wavelengths of blue and orange-red light, as is indicated by their peaks around 450-475 nm and around 650-675 nm.
