If the index of refraction of water is 1.33 what is the speed of light in water?

speed of light in water ##v=225407863.2 ##meter/second
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=225407863.2 ##m/sec
God bless….I hope the explanation is useful.
