What coloured wavelengths of light must be absorbed by green plants in photosynthesis?

A. White light is a mixture of coloured lights – red, orange, yellow, green, blue, indigo and violet. A green plant appears green because it reflects green light and doesn’t use it but absorbs the other colours of light. The main lights absorbed by a plant for photosynthesis are red and blue.
