उत्तर
The refractive indices of glass and water with respect to air are `3/2` respectively. The refractive index of glass with respect to water will be `bbunderline(9/8)`.
Explanation:
Given: Refractive index of glass w.r.t. air, `(n_(ag) = 3/2)`
Refractive index of water w.r.t. air, `(n_(aw) = 4/3)`
The refractive index of glass with respect to water is:
`n_(wg) = n_(ag")/n_(aw)`
= `(3/2)/(4/3)`
= `3/2 xx 3/4`
= `9/8`
