speed of light in water #v=225,407,863.2" "#meter/second

Explanation:

Formula for refractive index

#n=c/v# where #" " "n=" "#refractive index
#" "c=299792458" "#speed of light in a vacuum in
#" " #meter per second
#" "v=#phase velocity of light in the medium

Solve for #v#

#v=c/n#
#v=299792458/1.33#
#v=225,407,863.2" "#m/sec

God bless....I hope the explanation is useful.
