Question

A ray of light in air is 3×10^8m/s and the speed of light in water is 2.26×10^8m/s. Find the refractive index of water

Answer 1

Answer:divide 3.0 ×10^8 ÷ 2.26×10^8

Explanation:

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 .
