Answer:
Chlorophyll a- violet blue
Chlorophyll b - orange red
Carotenoids- green yellow
Explanation:
The three major plant pigments are chlorophyll a, chlorophyll b and carotenoids.
Various pigments are identified by their specific pattern of wavelength absorption in the spectrum of visible light. Chlorophyll a absorbs light in the violet-blue region, while chlorophyll b absorbs orange-red light. Chlorophyll a and b reflects or transmits green light hence they appear green. Carotenoids absorb light in the green - yellow region hence they reflect longer yellow, red, and orange light.
