AI Generated Solution

To solve the problem, we need to find the smallest distance from the source \( S_2 \) on a line perpendicular to the line joining the two sources \( S_1 \) and \( S_2 \) where a minimum intensity occurs. ### Step-by-Step Solution: 1. **Understanding the Setup**: - We have two coherent point sources \( S_1 \) and \( S_2 \) separated by a distance \( d = 2\lambda \). - The light from these sources will interfere, creating a pattern of constructive and destructive interference. ...
