Solution

The correct option is C $1.732$
Given,

The relative permeability of glass is $ρ_{R} = \frac{3}{8}$

The dielectric constant of the glass is $ε_{G} = 8$

Hence the refractive index is given as

$μ_{G} = \sqrt{ρ_{G} \times ε_{R}}$

$μ_{G} = \sqrt{8 \times \frac{3}{8}}$

$∴ μ_{G} = \sqrt{3} \approx 1.732$ .
