How much time will light take to cross 2 mm thick glass pane if refractive index of glassis `3//2`?

Explanation

To find out how much time light will take to cross a 2 mm thick glass pane with a refractive index of \( \frac{3}{2} \), we can follow these steps:

### Step 1: Understand the relationship between speed of light, refractive index, and time.
The refractive index \( n \) of a medium is defined as:
\[ n = \frac{c}{v} \]
where:
