hey dude,
i cant tell you what prac we did to find it out cos i dont remember but i can tell you that blue-green light (500nm) is the most effective for the human eye. red and ultra-violet light are much less effective. from memory we did this by looking at the electromagnetic spectrum..... duno if that helps but good luck
