The bending of light when it travels from one medium to another having different refractive indices is called ____.
The following table gives the values of 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.
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 |
