Question

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

Answer 1

Answer:

Explanation:

The speed of light in carbon di sulphide is 1/163 times the speed of light

in vacuum..

In other words the refractive index of a medium is the measure of speed of light in that medium.It is expressed as the 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 the medium given

So speed of ligt in carbondisulphide=3*10^8/1.63=1.84*10^8m/sec..
