Unformatted text preview: 20. Let the distance in question be x. The path difference (between rays originating from S1 and S2 and arriving at points on the x > 0 axis) is d2 + x2 − x = m+ 1 2 λ, where we are requiring destructive interference (half-integer wavelength phase differences) and m = 0, 1, 2, · · · . After some algebraic steps, we solve for the distance in terms of m: x= d2 (2m + 1)λ − . (2m + 1)λ 4 To obtain the largest value of x, we set m = 0: x0 = d2 λ (3.00λ)2 λ −= − = 8.75λ . λ 4 λ 4 ...
