Two speakers separated by a distance of 4.30 m. the speakers are in phase with one another. A person listens from a location 2.80 m directly in front of one of the speakers. Assume the speed of sound of 343 m/s.
(a) Find the difference in distance from the two speakers tp the person.
(b) Find the maximum wavelength that gives destructive interference.
(c) Find the lowest frequency that gives destructive interference.
