Answer 2

Answer:

thanks for fre e point

Explanation:

the refractive index of water is 4/3,

To Find :-

Velocity of water

Solution :-

We know that

ng = c/v

ng = Refractive Index

c = Speed of light in vaccum

v = Speed of the given medium

4/3 = 3 × 10⁸/v

4 × v = 3 × (3 × 10⁸)

4v = 9 × 10⁸

9 × 10⁸/4 = v

2.25 × 10⁸/1 = v

2.25 × 10⁸\begin{gathered}\\\end{gathered}
