Answer:
Given, refractive index of water = 4/3
Speed of light in air = 3 x 10^8
Let, speed of light in water = s
Now, using formula,
Refractive index = speed of light in air/ speed of light in medium(given)
4/3 = 3 x 10^8 / s
s = 9 x 10^8 / 4 [cross multiplying]
s = 2.25 x 10^8 m/sec

refractive index u = 4/3
u = c/v
v = c / u
v = 3 × 10^8 / ( 4/3 )
v = 9/4 × 10^8
v = 2.25 × 10^8 m/s
