How does wavelength and light intensity affect the rate of photosynthesis?
Divya is correct. In fact, there are molecules that are very important in photosynthesis known as P680 and P700, and these are so named because of the wavelength (nm) of light they are most productive with. Both 680 and 700 nm light fall well within the red light band; blue light is also very effective because different chlorophyll molecules that transfer energy to the photosynthesis reaction site are sensitive to blue light. You can tell inductively that green light is least effective because the photosynthetic parts of plants are green; therefore they reflect green light and absorb very little for photosynthesis.
