Unformatted text preview: 26. Fig. 36-9 in the textbook is plotted versus the phase difference (in radians), whereas this problem requests that we plot the intensity versus the physical angle θ (defined in Fig. 36-8). The values given in the problem imply dλ = 1000. Combining this with Eq. 36-22 and Eq. 36-21, we solve for the (normalized) intensity: I = cos2 (1000π sin θ) . 4I0 This is plotted over 0 ≤ θ ≤ 0.0040 rad: 1 0.8 0.6 0.4 0.2 0 0.001 0.002 theta 0.003 0.004 ...
