Two stereo speakers are separated by 9.0 m. The speakers can be made to issue the same frequency note in phase. A listener stands at the midpoint of the line joining the speakers. She then takes a step of 0.75 m closer to one of the speakers. At this new position, f₁ is the lowest frequency where there is destructive interference and f2 is the lowest frequency where she would hear constructive interference. (The speed of sound in air is 340 m/s.) f₁ and f2 are: ( 226, 340 Hz 113, 67 HZ ( 113, 226 Hz 67, 170 Hz 170, 340 Hz
