(numbers 11-12) Speakers C and D emit the same pure tone of wavelength 1.6 m, are exactly in phase, and are 3.6 m apart. 11. An observer begins at point P, equidistant to the two speakers, and moves directly to point Q along the path shown. Point Q is the position of the 2nd quiet spot (completely destructive interference) observed during this process. Point Q is further from D than from C. a) 1.6 m с b) 1.8 m c) 2.1 m d) 2.4 m e) 2.7 m D a) 0 b) 1 c) 2 P *may not be drawn to scale 12. How many quiet spots (completely destructive interference) exist along the line segment connecting the speakers?
