Refractive index of diamond with respect to glass is 1.6. If the absolute refractive index of glass is 1.5, then the absolute refractive index of diamond is

Absolute refractive index of glass =

Refractive index of diamond w.r.t glass is



⇒ μdiamond = 1.6 × μglass


⇒ μdiamond = 1.6 × 1.5 (μglass = 1.5).


⇒ μdiamond = 2.4


Hence the absolute refractive index of diamond is 2.4. Therefore the option B is correct.
