Why is it that plants grow better under a green light? I observed in different experiments as the place where u put the plants in the transparent color (like cellophane, for example) and then grow that way, some in green, grow better in comparison to those of less blue, red, yellow and transparent. I want to know, as an important cause of practical reasons making this survey project:) u know, I mean, not only because the plants are green ... stuff like that ...
If you shine pure white light on a plant, it absorbs all colors except those photons reflected into the eye (where the black absorbs all the photons and white reflects all the photons). If a plant is green it reflects photons that look green (blue + yellow). You may have to take into account the primary colors and mixing colors. What you see is a mixture of colors perceived by the three types of cones sensitive to color on the retina (blue and yellow mix to see green, etc..)
