What is the speed of light in diamond if its refractive index is 2.41 ?

Explanation

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

### Step-by-Step Solution:

1. **Understand the Concept of Refractive Index**:
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}
