Refractive indices of different materials are given. Find out through which medium light passes with maximum speed.
Speed of light is maximum in Water.
The refractive indices of any medium are inversely proportional to the speed of light in it. We can see from the formula of refractive indices:
Speed glass =
=
Similarly, for,
Speed glycerine = 
Speed sunflower oil = 
Speed water = 
Speed Flint glass = 
Here we see that,
Speed water > Speed glycerine > Speed glass > Speed Flint glass > Speed sunflower oil
We can also say that greater the refractive indices lesser will be speed.
