1. The problem statement, all variables and given/known data Why is the index of refraction in lighter colors of Jell-O higher than the index of refraction of darker colors of Jell-O, and why is the speed of light faster in lighter colors of Jell-O? 2. Relevant equations 3. The attempt at a solution I know the refractive index of the different colors of Jell-O are between 1.30-1.40. Note: I'm an 8th grader, I just need help with my Science fair project.
