Engelmann's experiment, which involved exposing different segments of algae to various colors of light and observing the distribution of aerobic bacteria (which are attracted to oxygen), was designed to determine if photosynthesis is impacted by the color of light. The bacteria congregated in areas of highest oxygen production, indirectly showing which colors of light were most effective for photosynthesis.
