To solve the problem of obtaining the expression for the width of the interference fringes in Young's double-slit experiment, we will follow these steps: ### Step-by-Step Solution: 1. **Understanding the Setup**: - We have two slits \( S_1 \) and \( S_2 \) separated by a distance \( d \). - The screen is placed at a distance \( D \) from the slits. - A point \( P \) on the screen is at a distance \( x \) from the central maximum \( O \). ...
