The phase difference between two waves meeting at a point is `3 pi/2`. What is the corresponding path difference ?

Explanation

To find the path difference corresponding to a phase difference of \( \frac{3\pi}{2} \), we can use the relationship between phase difference and path difference.

### Step-by-Step Solution:

1. **Understand the Relationship**: The phase difference \( \phi \) between two waves is related to the path difference \( \Delta x \) by the formula:
\[ \phi = k \Delta x \]
