In the figure given below, the lighter line (upper) indicates the action spectrum for photosynthesis and the black line (lower) indicates the absorption spectrum of chlorophyll a. Answer the following
a. What does the action spectrum indicate? How can we plot an action spectrum?

b. How can we derive an absorption spectrum for any substance?

Solution: a. The photosynthetic rate is indicated by the action spectrum. The measurement is oxygen release, which can be compared to the action spectrum by looking at the oxygen releases on the y-axis and the wavelength on the x-axis.

b. Processing can be used to absorb certain wavelengths for a specific pigment, like as chlorophyll-a, chlorophyll-b, or any other pigment.
