No interference pattern is detected when two coherent sources are infinitely close to each other. Why?

General instruction same as in chapter 1. Assertion: No interference pattern is detected when two coherent sources are infinitely close to each other. Reason:The Fringe width is inversly proportional to the distance between the two slits and a singel fringe may occupy the whole screen.

Assertion (A) : No interfrence pattern is detected when two coherent sources are very closer to each other. (i.e separation almost zero) Reason (R ) : The fringe width is inversely proportional to the distance between the two slits

Why interference pattern not detected when two coherent sources are far apart.

Why is interference pattern not detected when two coherent sources are far apart?

A : When the coherent sources are far apart, interference pattern cannot be detected. R : If two point coherent sources are infinitely close to each other, firinges appears very sharp.
