Question

If refractive index of glass w.r.t air is 3/2 and refractive index of water w. r. t air is 4/3. Find refractive index of glass w. r. t water.
plzzz​

Answer 1

8/9

Explanation:

REFRACTIVE INDEX OF GLASS/AIR = 3/2

AND. WATER/AIR = 4/3

THEREFORE,

REFRACTIVE INDEX OF WATER/GLASS WILL BE :-

= 4/3/3/2

= 4/3 × 2/3

= 8/9

or you can solve it , 8/9 = 1.125

Answer 2

Answer:

9/8

Explanation:

refractive index of glass wrt air = 3/2

refractive index of water wrt air = 4/3

then , refractive index of glass wrt water = 3/2/4/3 = 9/8
