Quizplus · Accepted Answer

Engelmann's experiment was designed to determine if photosynthesis is impacted by the color of light. He used bacteria to measure the oxygen production and found that the most oxygen was produced in the areas of the spectrum where chlorophyll absorbs light the most, indicating that photosynthesis is most efficient in these areas.
