The first action spectrum was studied by T.W.Engelmann(1882) by using green algae like cladophora which liberated Oxygen according to the rate of photosynthesis in different wavelengths of light. Oxygen loving bacteria were used to find out the amount of Oxygen liberated
The graph obtained was almost parallel to the absorption spectrum of Chlorophyll A .
(For spectrum, Refer to the Image attached.)

Answer:
Explanation:
1. T.W Engelmann(1843-1909), using a prism he spilt light into its spectral components and then illuminated a green alga, Cladophora he placed in a suspension of aerobic bacteria.
2.The bacteria detect the sites of o2 evolution.
3. He observed that bacteria accumulated mainly in the region of blue and red light of the spilt spectrum.
4. A first action of spectrum was described.
5. It resembles roughly the absorption spectra of chlorophyll a and b.
