Two loudspeakers in a plane, 5.0 m apart, are playing the same frequency. if you stand 11.0 m in front of the plane of the speakers, centered between them, you hear a sound of maximum intensity. as you walk parallel to the plane of the speakers, staying 11.0 m in front of them, you first hear a minimum of sound intensity when you are directly in front of one of the speakers. part a)what is the frequency of the sound? assume a sound speed of 340 m/s. i got 120.02 hz. this is right, i checked. part b)if you stay 12.0 m directly in front of one of the speakers, for what other frequencies between 100 hz and 700 hz is there a minimum sound intensity at this point?
