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