Changes in photosynthetic rate with different wavelengths of light.

The rate of photosynthesis varies greatly with changes in wavelengths of light. Light's color is determined by its wavelength of light, and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. The rate of photosynthesis can be measured in several ways, but the easiest and most efficient way to measure the rate of photosynthesis would be through counting the number of air bubbles …

…occurring in each plant can be measured through the number of bubbles emerging from the plant, which allows one to determine which color is the most beneficial for photosynthesis. This happens to be purple light, for it contains the most energy. Thus, varying wavelengths of light have drastic affects on the rate of photosynthesis, which can be seen by counting the number of bubbles produced by a submerged Elodea plant in different colors of light.
