Answer 2

Answer:

given data:

refractive index of glass with respect to air =3/2

refractive index of water with respect to air=4/3

to find:

refractive index of glass with respect to water=?

calculations:

$refractive \: index \: of \: glass \: with \: respect \: to \: water \\ = \frac{ (\frac{4}{3}) }{ (\frac{3}{2}) } \\ = \frac{4 \times 2}{3 \times 3} \\ = \frac{8}{9}$

your answer is 8/9
