In a single slit diffraction experiment, the width of the slit is made double the original width. How does this affect the size and intensity of the central diffraction band ?

Explanation

To analyze how doubling the width of the slit in a single slit diffraction experiment affects the size and intensity of the central diffraction band, we can follow these steps:

### Step 1: Understand the formula for the width of the central maximum
The width of the central maximum in a single slit diffraction pattern is given by the formula:
\[ V_0 = \frac{2D\lambda}{d} \]
where:
- \( V_0 \) is the width of the central maximum,
- \( D \) is the distance from the slit to the screen,
