I have been trying to find out how the refractive index of water is 
calculated.  I believe, to a close approximation, that the refractive index is 
given by square-root(K) where K is the dielectric constant.  K for water is 80 
and the refractive index for water is 1.33.  This does not work out correctly.  
Please explain
