by using Snell's law
n1/n2=V2/V1
as refractive index of air is considered to be 1
so
3/4=V2/3*10^8
v2= 9*10^8/4
v2=2.25*10^8
n1/n2=V2/V1
as refractive index of air is considered to be 1
so
3/4=V2/3*10^8
v2= 9*10^8/4
v2=2.25*10^8

refractive index=speed of light in air/speed of light in water
2.25×10^8=speed of light in water
2.25×10^8=speed of light in water
