How would the angular separation of interence fringes in Young's double slit experiment change when the distance between the slits and screen is halved ?

Explanation

To solve the question regarding how the angular separation of interference fringes in Young's double slit experiment changes when the distance between the slits and the screen is halved, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Angular Separation**:
The angular separation (β) of the interference fringes in Young's double slit experiment is given by the formula:
\[
\beta = \frac{\lambda}{d} \cdot \frac{D}{D}
