# Is metal electrical conductivity correlated with optical reflectivity?

Silver is metal with highest electrical conductivity.I read that it have highest optical reflectivity,that it shines most from all metals.

Is there link between conductivity and how shiny the metal appears? Please assume clean surface,no surface oxidation.

$R$=$1$-$4 \sqrt{\frac{\nu \pi \epsilon_0} {\sigma}}$
