Hey, I'm trying to make three LED lights that each are one of the primary colors of light. But, after discovering real fast that Radioshack doesn't sell the right kind, I asked my physics teacher for help. He said I need to go out and find the wavelengths of the three colors. And here I am! So, the question is: What are the wavelengths of the primary colors of light? I feel like I should be able to find it online but I'm having some trouble. Thanks.
