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.
