44. (a) At the left end, the plates touch, so L = 0 there, which is clearly consistent with Eq. 36-35 (the destructive interference or “dark fringe” equation) for m =0. (b) Eq. 36-35 shows a simple proportionality between L and λ . So as we slowly increase L (from zero – its value in part (a)), the smallest nonzero value of
