Question:
Refractive index of diamond with respect to glass is 1.6 and absolute refractive index of glass is 1.5.
Find out the absolute refractive index of diamond.
Solution:
$n_{d g}=1.6$ and $n_{g u}=1.5$
$n_{\alpha}^{\circ}=?$
Now $n_{d g}=\frac{n_{d a}}{n_{g a}}$
$\therefore n_{d u}=n_{d_{d}} \times n_{s e}=1.6 \times 1.5=2.4$
