Question

out of the following which has the highest absolute refractive index 1)fused quartz 2) diamond 3) crown glass 4)ruby glass

Answer 1

Diamond it will right ask another one

Answer 2

We know that,

The refractive index of given material,

The refractive index of fused quartz is 1.46

The refractive index of diamond is 2.42

The refractive index of crown glass is 1.52

The refractive index of ruby glass 1.76

According to refractive index,

$\mu_{d} > \mu_{ruby} > \mu_{crown} >\mu_{fused\ quartz}$

Hence, Diamond has the highest absolute refractive 2.42.
