Two loudspeakers placed 6.0 m apart are driven in phase by an audio oscillator whose frequency range is 2193 Hz to 2967 Hz.
 
  A point P is located 4.4 m from one loudspeaker and 3.6 m from the other. The speed of sound is 344 m/s. The frequency produced by the oscillator, for which constructive interference of sound occurs at point P, is closest to
  A) 2580 Hz.
  B) 2903 Hz.
  C) 2473 Hz.
  D) 2795 Hz.
  E) 2688 Hz.

Question 2

The sound from a single source can reach point O by two different paths. One path is 20.0 m long and the second path is 21.0 m long. The sound destructively interferes at point O.
 
  What is the minimum frequency of the source if the speed of sound is 340 m/s? A) 340 Hz
  B) 6800 Hz
  C) 520 Hz
  D) 680 Hz
  E) 170 Hz
