Refractive index of water is `4/3` and that of glass is `3/2` . What is the refractive index of glass with respect to water ?

A

`9/8`

B

`8/9`

C

2

D

`1/2`

Text Solution

Verified by Experts

The correct Answer is:
A
Refractive index of glass in air = `n_(31)`
Refractive index of glass in water = `n_(32)`
Refractive index of water in air = `n_(21)`
`n_(31)=n_(32)xxn_(21)=(n_(31))/(n_(21))=(3//2)/(4//3)=9/8`
