Question

THE SPEED OF THE LIGHT IN VACUUM IS 3 X 10⁸ m/s AND IN WATER IS 2.25x10⁸ m/s.find the refractive index of water with respect to vacuum​

Answer 1

Answer:

Speed of light in vacuum = 3.0 x 108m/s

Speed of light in water = 2.25 x 108m/s

Refractive index of water = ?

We know that

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

Refractive index of water = 3 x 108/2.25 x 108 = 1.33
