Refractive index = Speed of light in vaccum / Speed of light in water. It is denotes as n = c / v, v = c / n= 3 × 10^8 m/s / (1.33) = 2.25 × 10^8 m/s.
Therefore, refractive index of the water can be measure by the Speed of light in water is 2.25 × 10^8 m/s.

Answer:
2.25 × 10⁸ m / sec
Explanation:
Given :
Refractive index of water = 1.33
Speed of light in air = 3 × 10⁸ m / sec.
We know :
Refractive index = Speed of light in air / Speed of light in water
Speed of light in water = Speed of light in air / Refractive index.
Putting value we get :
Speed of light in water = 3 × 10⁸ m / sec / 1.33 .
Speed of light in water = 2.25 × 10⁸ m / sec
Hence speed of light in water is 2.25 × 10⁸ m / sec
