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 same species and ages are placed each under (respecting their photoperiods) light sources emitting only one of the colours of the light spectrum (violet, anil, blue, green, yellow and red). The experiment is executed with each of the colours and after days each plant’s development is compared. Those plants whose development was normal performed satisfactory photosynthesis while 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 favour photosynthesis (curiously green is the light that plants “dislike”).
