`n=(v)/(c)` where n denotes the refractive index of a medium, v the speed of light in the medium and c the speed of light in vacuum.

Text Solution

AI Generated Solution

To determine whether the statement \( n = \frac{v}{c} \) is true or false, we will analyze the relationship between the refractive index and the speeds of light in different media. ### Step 1: Understand the Definitions - **Refractive Index (n)**: It is defined as the ratio of the speed of light in vacuum (c) to the speed of light in a medium (v). \[ n = \frac{c}{v} \] ...
