Answer:
Difference in speed of light in glass and water = 2.505*10⁷ m/s
Refractive Index of water = 4/3
Refractive Index of glass = 3/2
Refractive Index of water (u₁) = c/V₁
= V₁ = c/u₁
Refractive Index of glass (u₂) = c/V₂
= V₂ = c/u₂
According to question,
= V₁-V₂ = c/u₁ - c/u₂
= 2.505*10⁷ = c[3/4 - 2/3]
= 2.505*10⁷ = c[ (9-8)/12 ]
= 2.505*10⁷ = c/12
= 2.505*12*10⁷ = c
= 3.006*10⁸m/s = c (Speed of Light in Air)
I hope this helps.
