Both drawings show the same square, each of which has a side oflength L = 0.88 m. An observer O is stationed at onecorner of each square. Two loudspeakers are located at corners ofthe square, as in either drawing 1 or drawing 2. The speakers produce the same single-frequency tone in either drawing and are inphase. The speed of sound is 343 m/s. Find the single smallest frequency that will produce both constructive interference indrawing 1 and destructive interference in drawing 2.
