Question

the speed of light in water is 2.25 x 10^8 m/s and that in glass is 2 x 10^8 m/s . find the refractive index of the glass with respect to water ?

Answer 1

Answer:

1.33

Explanation:

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
