How will the interference pattern in Youngs double slit experiment change, when distance between the slits `S_1 and S_2` are reduced

Explanation

To understand how the interference pattern in Young's double slit experiment changes when the distance between the slits \( S_1 \) and \( S_2 \) is reduced, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
- In Young's double slit experiment, two slits \( S_1 \) and \( S_2 \) are separated by a distance \( D \).
- A screen is placed at a distance \( d \) from the slits to observe the interference pattern.
