We have the formula n = c/v; where n is the index of refraction, c is the speed of light in vaccum and v is the speed of light in the given medium.
Here we have
c = 3 x 10^8 m/s
n = 1.33
Hence v = 2.25 x 10^8 m/s
Hence the speed of light in water is 2.25 x 10^8 m/s
Here we have
c = 3 x 10^8 m/s
n = 1.33
Hence v = 2.25 x 10^8 m/s
Hence the speed of light in water is 2.25 x 10^8 m/s

Answer:
Step-by-step explanation:
Refractive index = Speed of light in vaccum / Speed of light in water. It is denotes as n = c / v, v = c / n= 3 × 10^8 m/s / (1.33) = 2.25 × 10^8 m/s.
Therefore, refractive index of the water can be measure by the Speed of light in water is 2.25 × 10^8 m/s.
