Question

Which colour of light gives maximum absorption peak of chlorophyll?

Answer 1

Absorption spectrum
The graph shows the absorption spectrum of a mixture of chlorophyll a, chlorophyll b and carotenoids in the range of visible light.
Chlorophyll a and chlorophyll b shows maximum absorption in the blue-red region of the light spectrum. Chlorophyll appears green as neither chlorophyll a nor b absorb green light.
Carotenoids absorb maximum light in the blue-green and violet region.
