View SolutionThe following table gives the values of refractive indices of a few media:
$S.No.$ $1$ $2$ $3$ $4$ $5$ 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 $(i)$ a medium pair so that light speeds up when it goes from one of these media to another. $(ii)$ a medium pair so that light slows down when it goes from one of these media to another.
| $S.No.$ | $1$ | $2$ | $3$ | $4$ | $5$ |
| Medium | Water | Crown glass | Rock salt | Ruby | Diamond |
| Refractive index | $1.33$ | $1.52$ | $1.54$ | $1.71$ | $2.42$ |
