T.W. Engelmann used aerobic bacteria to detect oxygen evolution. Which type of graph plots the effectiveness of different wavelengths of light in driving photosynthesis?
Q1. T.W. Engelmann used aerobic bacteria to detect oxygen evolution. Which type of graph plots the effectiveness of different wavelengths of light in driving photosynthesis?
Answer: Action spectrum
Explanation: The action spectrum shows the relative effectiveness of different wavelengths. Option B is wrong because the absorption spectrum only shows light uptake.
