Hi,
My name is Shaniya and I am a Year 10 student at Alfriston College.
I was wondering if you could tell me exactly why blue light has an
effect on vegetation plants.
Any other information relating to this would be helpful.
This research is for my science project.
The answer to this would be highly appreciated.

Blue light has a shorter frequency than red or green and
thus has more energy. I.e.., it works better.

There are a few different forms of chlorophyll, they repspond to different
wavelengths. Chlorophyll b responds to a peak of arround 480 nanometers
(greeny/blue light) That'l give you a bit to start with, given it's a
gread ten project you might or might not go to look at the day effects of
light and flowering because wavelength and duration of radiation has some
effects there.

Happy researching.



As Cameron noted, you are going to need to start thinking in nanometers and
what plants react to the spectrum described with color.Exactly why does
"blue light" have an effect on vegetation? It is doubtful that all
vegetation is similar in its response to changes in the "blue light " region
of the spectrum.How *much* of the spectrum?Where, the beginning or end?Some
dropoff in the middle?
The nanometer reading at top and bottom of this "blue light" is how wide?
What is the growing cycle, the soil PH,the water quality and amount, where
is it on the globe-near the equator, where it is hot hot hot, or in the
tundra growing on the north side of trees, a sort of moss.(edible as well,
besides useable for a compass)?
If you are more specific, you can get a more specific answer.As specific as
you wanna make it.
