Question

If the absolute refractive indices of glass and water are 3/2 and 4/3 respectively, what is the refractive index of glass with respect to water?

Answer 1

Given,

Refractive index of glass = `3/2`

Refractive index of water = `4/3` 

Refractive index of glass with respect to water

= `"Refractive index of glass"/"Refractive index of water"`

On substituting the values, we get,

= `(3/2)/(4/3)`

= `9/8`

Hence, the refractive index of glass with respect to water is `9/8`.
