SUMMARY
The discussion centers on understanding the movement of interference fringes in a Michelson Interferometer as the distance between mirrors is adjusted. When the distance difference (d) between the two legs of the interferometer is zero, no fringes appear. As the distance difference increases, the fringes become smaller and appear to move inward, confirming that the radius of the smallest fringe is inversely proportional to d. Thus, rotating the knob clockwise increases the distance difference, causing the fringes to move inward.
