Let, refractive index of diamond with respect to air $=n_{D A}=$ absolute refractive index of diamond, refractive index of glass with respect to air $= n _{ GA }=$ absolute refractive index of glass, refractive index of diamond with respect to glass $= n _{ DG }$
Given,
$N _{ DG }=1.6$ and $n _{ GA }=1.5$
Now, $n _{ DG }=\frac{ n _{ DA }}{ n _{ GA }}$
$\Rightarrow n _{ DA }= n _{ DG } \times n _{ GA }$
$\Rightarrow n _{ DA }=1.6 \times 1.5=2.4$
Given,
$N _{ DG }=1.6$ and $n _{ GA }=1.5$
Now, $n _{ DG }=\frac{ n _{ DA }}{ n _{ GA }}$
$\Rightarrow n _{ DA }= n _{ DG } \times n _{ GA }$
$\Rightarrow n _{ DA }=1.6 \times 1.5=2.4$
