describe the experiment of t.w engelmann with figure..or a roug labelled diagram..
Dear student,
Theodor Wilhelm Engelmann designed an experiment to show the effect of different wavelength of light on photosynthesis. He placed spirogyra (green algae) in a drop of water where aerophilic bacteria was present which acts as an indicator of oxygen. He illuminated spirogyra with different wavelength of light with the help of prism. Then he observed under microscope that the aerophilic bacteria was collected in the region of red and blue light and then he concluded that red and blue lights are the most effective lights for photosynthesis.
Regards
