Absorption spectrum
- The absorption spectrum is an indication of the wavelength of light absorbed by each pigment.
- It is measured using a spectrophotometer.
- A spectrophotometer is a machine that sends light through pigments and measures the fraction of light transmitted by each wavelength.
- Hence, the absorption spectrum is the graph plotting light absorption versus wavelength of that light.
- The absorption spectra of chloroplast pigments provide an insight into the relative effectiveness of different wavelengths of light for driving photosynthesis.
- Chlorophyll absorbs more of blue-violet wavelength than the red.
- The absorption spectrum is chiefly blue and red for chlorophyll.
- Chlorophyll a absorbs more of red wavelength than chlorophyll b.
