Sound source A is located at x = 0, y = 0, andsound source B isplace at x = 0, y = 2.9 m.The two sources radiate coherently inphase.An observer at x = 70 m, y = 0 notes thatas she takes a fewsteps in either the positiveor negative y direction away from y =0, thesound intensity diminishes.What is the lowest frequency ofthe sourcesthat can account for that observation?Answer in units ofHz.What is the next higher frequency of thesources that can accountfor that observation?Answer in units of Hz.
