Refractive index of material X with respect to air is 1.5. Refractive index of material Y with respect to air is 1.34. Find the refractive index of material X with respect to material Y.

Explanation

To find the refractive index of material X with respect to material Y, we can use the relationship between the refractive indices of the materials with respect to air.

### Step-by-Step Solution:

1. **Understand the Refractive Index**:
The refractive index (n) of a material with respect to air is defined as the ratio of the speed of light in air (c) to the speed of light in that material (v).
\[
n = \frac{c}{v}
