Answer:
Originally, the central fringe of newtons rings experiment will be dark because the incident light waves suffer a phase change of 180 degrees and hence instead of a bright central fringe, a dark central circular fringe is formed…. However if a dust particle or a very small obstacle comes in the way of the incident light waves, it will be enough to change the phase of the incident light waves again and hence, we will have a central bright spot
Hope this helps you....
