What is the speed of light in water? in glycerine?

You can search this speed….

##n=C/V##

##N##=Refraction Indice ##C##= Speed of light ##V##=Speed in the diferente mean

Are you agree to me that ##n=c/v## is equals ## v=c/n?##

So…. if## C=300.000( km )/s##

and the Water Refraction:## 1,333## and the Glycerine Refraction:## 1,9##

We find that the speed in this mean are aprox:

WATER## 225.500( km)/s## GLYCERINE: ##157,800( km)/s##
