Theodor Engelmann's famous experiment on which wavelengths of light drive photosynthesis. What result of Engelmann's experiment indicated to him which wavelength(s) was/were the best driver(s) of photosynthesis?

Expert Solution

Theoder Engelmann used oxygen loving or aerophilic bacteria on the Spirogyra algae that he used in the experiment . The algae contained chloroplast, which were long and spiral. He placed the bacteria on the algae and let white light of the sun pass through a prism. This soon produeced light in the visible spectrum. He proposed that oxygen production of the bacteria would be the most where the oxygen absorption would be the most and these where noticed in the red and blue wavelength of the visible light. So he concluded that plants absorbed red and violet or blue wavelengths of light and emitted green. He also concluded that blue and red wavelength of the light spectrum were the best drivers of photosynthesis.

Green plants use light from the Sun to drive photosynthesis. Photosynthesis is a chemical reaction in which water H2O and carbon dioxide CO2 chemically react to form the simple sugar glucose C6H12O6 and oxygen gas O2 . What mass of carbon dioxide is consumed by the reaction of 5.4g of water? Round your answer to 2 significant digits.

Two coherent wavelengths of light are incident on a double slit, one of the wavelengths corresponds to blue light of 460 nm and the other is unknown. The slit separation is 0.007 mm. The second-order bright fringe of the blue light falls at the same angle as the first order light of the other wavelength. (a) Determine the unknown wavelength. (b) Determine the number of fringes of these two wavelengths visible to one side of the zeroth order bright fringe....

In a photosynthesis experiment where DPIP was used to indicate when photosynthesis is occurring, the change in the % transmittance was measured with a spectrophotometer and results were recorded. The measurements were made after 20 min incubation of DPIP with unboiled chloroplasts in presence of a flood light at four pHs – 5.8, 6.8, 7.8 & 8.8 – and results obtained are indicated in the table below. pH % Transmittance 5.6 20 30 46 52 6.8 30 50 60 70...
