Refractive Index of glass with respect to water is
         
       
      
      
      
          
      
      
          Answer & Explanation
         Answer: D) 8/9         
         
Explanation: Refractive Index of glass with respect to water can be calculated by 
(Refractive Index of glass with respect to air) × (1/Refractive Index of water with respect to air)
 
We know that,
Refractive Index of glass with respect to air = 4/3
Refractive index of water with respect to air = 3/2
 
Hence, Refractive Index of glass with respect to water = (4/3) x (2/3) = 8/9.
