Chapter 37 387 P37.14 The path difference between rays 1 and 2 is: δθ θ =− dd sin sin 12 . For constructive interference, this path difference must be equal to an integral number of wavelengths: ddm sin sin θθ λ −= , or dm sin sin θθλ bg . P37.15 (a) The path difference = d sin and when Ly >> δµ == ×× = −− yd L 1 80 10 1 50 10 140 193 10 193 24 6 .. . m m m m ej . (b) δ = × × = 643 10 300 6 7 . . . m m , or δλ = . (c) Point P will be a maximum since the path difference is an integer multiple of the wavelength.
