What should be the width of each slit to obtain `10` maxima of the double slit interference pattern within the central maximum of single slit diffraction pattern ? (NCERT Solved example)

Explanation

To solve the problem of finding the width of each slit to obtain 10 maxima of the double slit interference pattern within the central maximum of the single slit diffraction pattern, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
- We have a single slit of width \( a \) and two slits of width \( d \).
- The distance from the slits to the screen is \( D \).
- We want to fit 10 bright fringes (maxima) of the double slit interference pattern within the central maximum of the single slit diffraction pattern.
