    light slower in water than in Air

    Explanation:

    Air's refractive index is about 1.0003, while water's is about 1.3. This means that light is "slower" in water than air. This is because it's more likely to hit a molecule and then get re-emitted, lengthening the amount of time the light takes to get through a certain distance of the medium.
