The refractive index of water is `4 //3 ` and the speed of light in air is `3 xx 10^(8) m//s`.Find the speed of light in water.

Explanation

To find the speed of light in water given the refractive index and the speed of light in air, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Refractive Index Formula**:
The refractive index (n) of a medium is defined as the ratio of the speed of light in vacuum (c) to the speed of light in that medium (v). The formula is:
\[
n = \frac{c}{v}
