Question

What is "Total Pigment " on the absorption spectrum?

Answer 1

The absorption spectrum shows how strongly the pigments absorb at different wavelengths.

The absorption spectrum and action spectrum show that the wavelengths that are most strongly absorbed.

The shorter the wavelength, the more energy it contains. During photosynthesis the light energy is converted into chemical energy. The absorbed light excites electrons in the pigment molecules and the energy can be passed on to be used by the plant.
