2ndcose = mλ (3) 9. From Eq (3), is the order (m) of the center fringe larger or smaller than that of the edge fringe? 11. When circular fringes collapse to the center (i.e. fringes are being destroyed, rather than being created), is the mirror spacing increasing or decreasing? (Hint: use Eq(3), and similar reasoning to Q.9)
