A student conducted an experiment exploring the effect of different wavelengths of light on photosynthesis. The student measured the relative percent oxygen over a period of time. Based on what
you know about photosynthesis and the data above, explain the effect that different wavelengths of light
have on relative percent oxygen. Be sure to cite specific data points. You may use the visible light
