Find the time taken by light to travel a distance of 3 cm in glass. `(c = 3 xx 10^8 m//s` and refractive index of water = 4/3)

Explanation

To find the time taken by light to travel a distance of 3 cm in glass, we can follow these steps:

### Step 1: Understand the given values
- The speed of light in vacuum (c) = \(3 \times 10^8 \, \text{m/s}\)
- The refractive index of glass (not given directly, but we will assume it is similar to water for this example) = \( \frac{4}{3} \)
- Distance to travel = 3 cm = \(3 \times 10^{-2} \, \text{m}\)

### Step 2: Calculate the speed of light in glass
