Question

The refractive index of glass with respect to air is `3/2` and the refractive index of water with respect to air is `4/3`. The refractive index of glass with respect to water will be:

(a) 1.525
(b) 1.225
(c) 1.425
(d) 1.125

Answer 1

 1.125
      
Explanation:
Refractive index of glass with respect to water =  `"Refractive index of glass with respect to air"/"Refractive index of water with respect to air "` 

`(3/2)/(4/3)` 

=1.125
