Question

Caculate speed of light in water of refractive index 4/3 given speed of light in air 3*10^8ms^-1

Answer 1

answer for this question is 2.25 ×10power 8

Answer 2

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 .
