Two loudspeakers in a plane are 2.0 m apart and in phase with each other. Both emit 700 Hz sound waves into a room where the speed of sound is 341 m/s. A listener stands 5.0 m in front of the loudspeakers and 2.0 m to one side of the center. a)ls the interference at this point maximum constructive, maximum destructive, or in between? b)How will the situation differ if the loudspeakers are out of phase? Step 1: SKETCH the situation. Step 2: Draw the distance r₁ from source 1 to the point and the distance r₂ from source 2 to the point Step 3: Find 1 and 2, then calculate Ar. Step 4: Find the wavelength Step 5:Find the phase difference at that point.
