Question

the refractive index of carbon disulphide is 1.63 what is the meaning of this statement​

Answer 1

 · The refractive index of carbon disulphide is 1.63. What is the meaning of this statement in relation to speed of light? The refractive index of a diamond is 2.42.

Answer 2

The speed of Light in carbon disulphide is 1/163 times the speed of light in vacuum.

In other words

The refractive index of a medium is a measure of the speed of light in that medium. It is expressed as a ratio of speed of light in vacuum relative to that in the medium under consideration Refractive index=n=speed of light in vacuum/speed of light in give medium

speed of light in carbon disulphide =3×10^8m/s/1.63=1.84×10^8m/s
