Q:

Refractive Index of glass with respect to water is

A) 4/3 B) 9/8
C) 2/3 D) 8/9
 
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.
