Absorption Spectrum
A graph showing the relative amount of light absorbed by a pigment as a function of wavelength
Photosynthetic Action Spectrum
A graph showing the photosynthetic activity of chloroplasts as a function of wavelength
Where are the peak wavelengths for chlorophyll a on the absorption spectrum?
Approximately 440 and 660 nm -> purple and red light
Where are the peak wavelengths for photosynthesis on the action spectrum?
Approximately 440-550 and 650-690. -> purple, blue, orange and red light
