T.W. Engelmann experimented on Cladophora. He illuminated Cladophora with white light after passing through a prism. He used aerobic bacteria to detect the oxygen evolution site and observed that maximum bacteria accumulated in the blue and red region of the spectrum, indicating that maximum photosynthesis occurs in this region.
