The following table gives the values of refractive indices of a few media.

  1 2 3 4 5
Medium Water Crown glass Rock salt Ruby Diamond
Refractive index 1.33 1.52 1.54 1.71 2.42

Use this table to give an example of a medium pair so that light speeds up when it goes from one of these media to another.
