What should be the width of each slit to obtain n maxima of double slit pattern within the central maxima of single slit pattern?

Explanation

To determine the width of each slit in a double-slit experiment such that we can obtain \( n \) maxima of the double-slit pattern within the central maximum of the single-slit pattern, we need to use the principles of interference and diffraction.

### Step-by-Step Solution:

1. **Understand the Single-Slit Diffraction Pattern**:
The width of the central maximum in a single-slit diffraction pattern is determined by the formula:
\[
\theta = \frac{\lambda}{a}
