Question

The refractive index of glass with respect to air is 3/2 and that of water with respect to air is 4/3 . The refractive index of glass with respect to water is ?


a)1/3
b)9/8
c)8/9
d)1

Please explain your answer ): ♥️​

Answer 1

Answer:

9/8

Explanation:

use the same formula which I gave you right now in the earlier question.

divide both the refractive index with each other, i.e, 3/2 whole divided by 4/3

Answer 2

Answer:

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
