The velocity of light in first medium is `2.8 xx 10^8 "m s"^(-1)` and that in the second medium is `2.3 xx 10^8 m^(-1)`. Find the refractive index of medium 2 with respect to medium 1.

Explanation

To find the refractive index of medium 2 with respect to medium 1, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the formula for refractive index**:
The refractive index (μ) is defined as the ratio of the speed of light in a vacuum (or air) to the speed of light in the medium. The relationship between the refractive indices and the velocities of light in two different media can be expressed as:
\[
\frac{\mu_2}{\mu_1} = \frac{V_1}{V_2}
