Question

You are standing 2.5 m directly in front of one of the two loudspeakers shown in the figure. They are 3.0 m apart and both are playing a 686 Hz 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. What is the largest distance from the top speaker at which you would hear a minimum sound intensity? dmax = 17.9 m Correct Part B Previous Answers 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 = Submit Request Answer Part C Complete previous part(s) Figure < 1 of 1 2.5 m 3.0 m Walk Provide Feedback ? m Next >

          You are standing 2.5 m directly in front of one of the two
loudspeakers shown in the figure. They are 3.0 m apart
and both are playing a 686 Hz 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.
What is the largest distance from the top speaker at which you would hear a minimum sound
intensity?
dmax = 17.9 m
