Question

The refractive indices of water and diamond are 4/3 and 2.42 respectively. Find the speed of light in water and diamond. (c=3×100000000m/S)

Answer 1

Diamond’s typical refractive index is 2.42,
 so v=3.10^8/2.42
= 1.24.10^8 m/s
1.2*10^8 is the speed of light in diamond 
speed of light in water is 2.25*108m/s
please mark my answer as brainliest.......
