Unformatted text preview: do we mean and how does it relate to the color of the pigment? The absorbance spectrum of a pigment is a measure of the degree to which the pigment absorbs particular frequencies/wavelengths of light/electromagnetic radiation. Because the color of a pigment is determined by the frequencies it reflects, the color of the pigment is determined by the frequencies it does not absorb. B. Why can’t plants use infrared or radio wave frequencies of electromagnetic radiation to drive the light reactions of photosynthesis? Infrared and radio wave frequencies of light do not have sufficient energy (their frequencies are too low) to drive the light reactions....
