Explanation / Answer

c = 3*108 m/s
1 m / 3*108 m/s = 3.3e-9 = 3.3 ns

part-B

the speed of light in a vacuum, which is always 3.00*10^8.Use equation n=c/v and

find the velocity for water by using v=c/n = 3.00*10^8/1.33=2.26*10^8 m/s. Then

multiply this answer by the seconds found in part one of this problem. 3.3*10^-9

secondsWhen multiplied by the velocity of water you get 0.7458 m

part - C

find the velocity for water by using v=c/n = 3.00*10^8/1.5=2*10^8 m/s. Then

multiply this answer by the seconds found in part one of this problem. 3.3*10^-9

secondsWhen multiplied by the velocity of water you get 0.66 m

part - D

find the velocity for water by using v=c/n = 3.0*10^8/2.18=1.38*10^8 m/s. Then

multiply this answer by the seconds found in part one of this problem. 3.3*10^-9

secondsWhen multiplied by the velocity of water you get 0.46 m
