What will be the effect on the width of the central maxima if the slit it made narrower ?

Explanation

To solve the question, "What will be the effect on the width of the central maxima if the slit is made narrower?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Central Maxima**: The central maxima in a single-slit diffraction pattern is the brightest and widest part of the pattern formed when light passes through a slit.

2. **Defining Parameters**:
- Let \( b \) be the width of the slit.
