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
