22. (a) We use ∆ y = Dλ/d (see Sample Problem 36-2). Because of the placement of the mirror in the problem D =2(20 . 0m)=40 . 0 m, which we express in millimeters in the calculation below: d = y = (4 . 00 × 10 4 mm)(632 . 8 × 10 6 mm) 100 mm =0 . 253 mm . (b) In this case the interference pattern will be shifted. At the location of the original central maximum,
