12. Two identical speakers A and B are placed on the y-axis, while a sound detector is placed on the x-axis as shown in the figure below. The detector records a maximum intensity at that location. Find the two lowest frequencies emitted by the speakers that would produce an intensity maximum at the detector. Assume the speed of sound in air is 345 m/s. y В 2.40 m- detector 15.0 m
