Two cars are stuck in a traffic jam and each sounds its horn at a frequency of 669 Hz. A bicyclist between the two cars, r= 4.68 m from each horn (see the figure below), is disturbed to find she is at a point of constructive interference.
How far backward (in m) must she move to reach the nearest point of destructive interference? Take the speed of sound to be V= 343 m/s

Two identical speakers are spaced 12 m apart, aimed toward each other. They each play a 171.5 Hz tone with the same phase constant. A. If you stand at the center point between the speakers, the result of superposition of the sound waves from the speakers is constructive inteference. Explain. B. How far must you move from the center toward one of the speakers in m to reach the next point of destructive interference?

Two speakers are separated by two meters in a plane. They are in-phase. They project 891 Hz sound waves. The speed of sound is 343 m/s. Consider the point 5.0 m in front of one of the speakers, perpendicular to the plane of the speakers. At this point, is there maximum constructive interference, perfect destructive interference, or something in between?
