Find the velocity of light in a given medium. The absolute refractive index of the medium is 1.5 (given velocity of light in vacuum or air = `3xx10^8 " m s"^(-1)` ) .

Explanation

To find the velocity of light in a given medium using the absolute refractive index, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula**: The absolute 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 the medium (V). The formula is:
\[ \mu = \frac{C}{V} \]
