|
Chlorophylls absorb light of these wavelengths more than other wavelengths.
|
|
|
These are the only wavelengths that carotenoids cannot absorb.
|
|
|
Light of these wavelengths have the highest energy in the visible spectrum.
|
|
|
Light of these wavelengths activate the ATP synthase enzyme.

Detailed explanation-1: -The blue and red light spectrum is most efficient in photosynthesis because both photosystems (PS I and PS II) absorb light with wavelengths in the red range (680 and 700 nm, respectively). Carotenoids absorb blue light as well, passing the energy on to chlorophyll. Chlorophyll absorbs light in the red region.
Detailed explanation-2: -Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.
Detailed explanation-3: -Chlorophyll a is the most abundant pigment in plants. Chlorophyll a absorbs light mostly 430nm (blue) and 662nm (red) wavelength light. It reflects green light so it appears green to us.
Detailed explanation-4: -The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
Detailed explanation-5: -Photosynthesis depends on upon the absorption of light by pigments in the leaves of plants. The most important of these is chlorophyll a, but there are several accessory pigments that also contribute. Chlorophyll a absorbs its maximum energy from the blue and red wavelengths.
