Two speakers, facing each other, produce coherent sound waves that interfere destructively at a point that is ¾ of the way from one speaker to the other. If the speed of sound is 343 m/s, and the sound waves are emitted in phase at 880 Hz, which of the following is a possible distance between the two speakers?

a. 2.3 m b. 0.58 m c. 1.56 m d. 77 cm e. 2.7 m

Two loudspeakers emit coherent in phase sound waves with at a frequency of 68.8 Hz. The speed of sound is 344.0 m/s. Point q is vertically located 2.0 m from the bottom speaker and 5.0 m from the top speaker. At point q, is there maximum constructive interference, complete destructive interference, or neither??

Suppose two speakers are arranged such that they emit identical sound waves, and are separated by 4m. A microphone is positioned 3m above one of the speakers. If the speed of sound is 340 m/s, and both speakers start in phase, are turned on at the same time, and emit the same frequency, what is the lowest frequency such that the microphone picks up no sound? You may ignore amplitude reduction due to distance for this problem.
