One scientist cultured Cladophora in a suspension of Azotobacter and illuminated the culture by splitting light through a prism. He observed that bacteria accumulated mainly in the region of :
(1) Blue and red light
(2) Violet and green light
(3) Indigo and green light
(4) Orange and yellow light

Option (1)Blue and red light is correct.

This is because – Azotobacter is aerobic bacteria.nCladophora is green alga. T.W. Engelmann split light into its spectral components and detected that aerobic bacteria accumulated mainly in the region of blue and red light of the split spectrum.
