You are standing 2.5 mm directly in front of one of the two loudspeakers shown in the figure. They are 3.0 mm apart and both are playing a 686 HzHz tone in phase. (Figure 1) You may assume that the room is 20∘∘C in this example such that the speed of sound is 343 m/s.Part AWhat is the largest distance from the top speaker at which you would hear a minimum sound intensity?dmax =17.9mPart BIn the previous part, you figured out that the difference in path length between the two speakers must be a multiple of a half wavelength to get destructive interference. A path length difference of exactly half of a wavelength gave you the answer above. What distance will result if the path difference is 1.5 λ?d2 =5.63m Part CWhat distance will result if the path difference is 2.5 λ? d3 = m

Part A

What is the largest distance from the top speaker at which you would hear a minimum sound intensity?

dmax =

17.9

Part B

In the previous part, you figured out that the difference in path length between the two speakers must be a multiple of a half wavelength to get destructive interference. A path length difference of exactly half of a wavelength gave you the answer above. What distance will result if the path difference is 1.5 λ?

d2 =

5.63
