If speed of light in a medium is `2xx10^8m//sec`. Find refractive index of medium.

Explanation

To find the refractive index of the medium, we can follow these steps:

### Step 1: Understand the formula for refractive index
The refractive index (μ) 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 given by:
\[ \mu = \frac{C}{V} \]
