Homework Help: Light and Refraction

  1. Jul 16, 2007 #1
    Determine the time it takes for light to travel 54 cm through glycerine in an aquarium.

    Do I account for air, glycerine and glass???

    I would answer the precise question given. What's the speed of light in glycerine? How far does it travel through the glycerine? (Given no additional context, the fact that it's in an aquarium seems irrelevant.)
