Study the given graph which shows the action spectrum of A superimposed on B spectrum of chlorophyll

Question

Study the given graph which shows the action spectrum of A superimposed on B spectrum of chlorophyll $a$.\

Professor PC Thomas Classes · Answer

(d) : The graphical curve showing the amount of energy of different wavelengths of light absorbed by a pigment is called absorption spectrum. It is studied with the help of spectrophotometer. The absorption spectra of chlorophylls $a$ and $b$ show that they absorb maximum light in the blue-violet and red wavelengths. The pigments are often known after the wavelength which is absorbed to the maximum, e.g., $\mathrm{Chl} a_{673}, \mathrm{Chl} a_{683}\left(\mathrm{P}_{680}\right), \mathrm{Chl} a_{703}\left(\mathrm{P}_{700}\right)$.
