Question

# Following figure shows sources and that emits light of wavelength in all directions. The sources are exactly in phase and are separated by a distance equal to If we start at the indicated start point and travel along path 1 and 2, the interference produce a maxima all along

- Path 1
- Path 2
- Any path
- None of these

## The correct answer is: Path 1

### At any point along the path 1, path difference between the waves is 0.

Hence maxima is obtained all along the path 1.

At any point along the path 2, path difference is 1.5 l which is odd multiple of so minima is obtained all along the path 2
