Question

light travel through water with a speed of 2.25×10,8 m/s what is the refractive index of water i need full answer​

Answer 1

Answer:

1.33

Explanation:

Given :

Speed of light in water = 2.25 × 10⁸ m / sec

We're asked to find refractive index n :

We know :

Refractive index = Speed of light in vacuum / speed of light in given medium

= > n = c / v

where c = 3 × 10⁸ m / sec

Now putting values in equation we get :

= > n = 3 × 10⁸ / 2.25 × 10⁸

= > n = 3 / 2.25

= > n = 1.33

Therefore , refractive index of water is 1.33!
