Answer:
The answer is 0.75
Explanation:
The refractive index is the ration between seed of in vacuum to the speed of light in medium.
The refractive index of water for light going from air to water is 1.33.
So the refractive index for beam of light going from water to air will be the inverse of 1.33.
n = 1/ 1.33
n = 0.75
Thus the refractive index will be 0.75

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
