Answer:
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
