T. W. Engelmann did an experiment where he separated the wavelengths (colors) of light using a prism, and illuminated a chain of algae cells so that each cell received 1 color of light. He then added oxygen-loving bacteria to the mixture and saw that they preferentially went to the algae using red and blue light. He concluded (correctly) that red and blue light were the most efficiently used in photosynthesis (producing the most oxygen for the bacteria). Suppose that you did the same experiment, but did not use a prism to separate the wavelengths of light. Where will the bacteria go?
