The following table gives the refractive indices of a few media:
Use this table to give an example of:
(i) a medium pair so that light speeds up when it goes from one of these medium to another.
(ii) A medium pair so that light slows down when it goes from one of these medium to another.
(i) Example of a medium pair so that light speeds up when it goes from one of these medium to another is Crown glass to water
(ii) Example of A medium pair so that light slows down when it goes from one of these medium to another is Water to diamond
