A)8/9

B)9/8

C)2 √

D)1/2

Answer 2

Answer:

• Option (A) 8/9 is the required answer.

Explanation:

Given:-

• Refractive index of water to air = 4/3

• Refractive index of glass to air = 3/2

To Calculate:-

• Refractive index of glass with respect to water

Solution:-

Here , we have to calculate the relative refractive index between glass & water .

• Refractive index of glass with respect to Water = Refractive index of Water with respect to air/Refractive index of glass with respect to air

Substitute the value we get

→ Refractive Index of Glass with Water =4/3/3/2

→ Refractive Index of Glass with Water = 4×2/3×3

→ Refractive Index of Glass with Water = 8/9

• Hence, the refractive index of glass with respect to water is 8/9.

So, Option (A) 8/9 is the required answer.
