Question

The absolute refractive index of water is 1.36 What is the velocity of the light in Water ? (Velocity of light in vaccum 3×10rays to 8m/s​

Answer 1

Answer:

2.205 x 10^8

Explanation:

Refractive index = Speed of light in vacuum / Speed of light in water

Speed of light in water = Speed of light in vacuum / Refractive index

Speed of light in water = 3 x 10^8 / 1.36

Speed of light in water = 2.205 x 10^8.
