Answer 2

the velocity of light in water is 225,000 km/sec.

you easily calculate it by :-

         refractive index= speed of light in vaccum/ speed of light in medium

let speed of light in water be x

                  1.3=  300,000/x

                 x= 300,000/1.3

               x=near about 225,000 km/sec
