-4 CHAPTER 33 Wave Optics These are the same slits as in Exercise 5. Waves with the same wavelength are spreading out on the right side. a. Draw four paths, starting at the slits, at an angle 0₂ such that the wave along each path travels two wavelengths farther than the next wave. Also draw dashed lines at right angles to the travel direction. Your picture should look much like the figure of Exercise 5, but with the waves traveling at a different angle. Use a ruler! b. Do the same for four paths at angle 012 such that each wave travels one-half wavelength farther than the next wave. Ar=2A K
