Hey dear here is your answer!!!!
Refractive index = c/v
4/3=3*10^8/v
v=9*10^8/4
v=2.5*10^8m/s
Hope it helps!!!

Your answer is ---
Given, speed of light in air c = 3×10^8m/s
reflective index of water nw = 4/3
Let, speeds of light in water be cl
Therefore,
nw = c / cl
=> 4/3 = 3×10^8/cl
=> cl = (3×10^8 × 3)/4
=> cl = 2.25 × 10^8 m/s
Hence, speed of light in water is 2.25×10^8 m/s
