Two loudspeakers in a plane, 6.0 mm apart, are playing the same frequency. If you stand 12.0 mm 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 12.0 mm in front of them, you first hear a minimum of sound intensity when you are directly in front of one of the speakers. What is the frequency of the sound?
