Speed of light in glass is `2xx10^(8)ms^(-1)`. What is the refractive index of glass ?

Explanation

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

### Step-by-Step Solution:

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 the medium (V). The formula is:
\[
\mu = \frac{C}{V}
