The refractive index of denser medium with respect to rarer medium is 1.125. The difference between the velocities of light in the two media is `0.25 xx 10^8 m//s`. Find the velocities of light in the two media. `(c = 3 xx 10^8 m//s)`.

Explanation

To find the velocities of light in the two media, we can follow these steps:

### Step 1: Understand the given information
We know:
- The refractive index of the denser medium with respect to the rarer medium is \( n = 1.125 \).
- The difference in velocities of light in the two media is \( \Delta v = 0.25 \times 10^8 \, \text{m/s} \).
- The speed of light in vacuum is \( c = 3 \times 10^8 \, \text{m/s} \).
