Question

if the speed of light in wateris 2.25 x 10^8m/sand the speed in vaccum is 3x10 ^8 m/s calculate the reflexive index of water​

Answer 1

Answer:

Refractive index of water:

Speed of light in vacuum/ Speed of light in water

= 3 x 10^8/ 2.25 x 10^8

= 300/225

= 1.33

Thus, the refractive index of water is 1.33

Hope it helps. Cheers.
