What is an example of a lab experiment that shows the variation of the photosynthesis efficiency in relation to different photic energy frequencies to which the reaction is exposed? Was it expected that green light frequency favored the reaction?

The experiment: Plants of similar species and ages are placed each under (respecting their photoperiods) light sources emitting only one of the colors of the light spectrum (violet, anil, blue, green, yellow and red). The experiment is implemented with each of the colors and after days each plant's development is compared. Those plants whose development was normal performed satisfactory photosynthesis whereas those with abnormal development underused the offered light.

Chlorophyll is green because it reflects the green light frequency, i.e., it does not "use" the green range of the electromagnetic spectrum. Thus green light does not favor photosynthesis (curiously green is the light that plants "dislike").
