Two in-phase loudspeakers that emit sound with the same frequency are placed along a wall and are separated by a distance of 5.00 m. A person is standing 12.0 m away from the wall, equidistant from the loudspeakers. When the person moves 1.00 m parallel to the wall, she experiencesdestructive interference for the first time. What is the frequency of the sound? The speed of sound in air is 343 m/s.
Two loudspeakers, A and B, are separated by a distance of 2.0 m. The speakers emit sound waves at a frequency of 680 Hz that are exactly out of phase. The speed of sound is 343 m/s. What are the next three distances from speaker A along the +x axis will a points of destructive interference occur?
The figure below shows an overhead view of two identical sound sources that are a
distance of D = 2.74 meters apart and they are each sending out sound waves in air which
is at a temperature of 21.52°C.
The angle 0 is indicated
A person (the third circle in the figure), walks around a semicircle having its center at the
midpoint between the two speakers. If the person hears no sound when the angle 0 in the
figure is 0 = 60°, determine the minimum frequency of the sound waves coming from the
sources.

(b) 222 Hz
(c) 272 Hz
