B. What do you think are the three primary colors of LIGHT?

(Hint: What are the three color receptors that are in the retina of a human????)

C. Why do you think the primary colors of Light are different from the primary colors of ink & paint?

D. Compare your results to your hypothesis. Were they the same? If so, why? If not, why not?
