Two speakers are located at two neighboring corners of a square of side length 10.00 m. A listener walks from another corner of the square along the side toward the speaker next to her. Assume that the two speakers are playing the same 75.0-Hz tone in phase and the sound speed in the air is 343 m/s. (1) How far must she walk to reach a constructive interference point? (A) 1.05 m; (B) 1.35 m; (C) 1.65 m; (D) 1.95 m; (E) 2.25 m. (2) How far must she walk to reach a destructive interference point? (A) 2.14 m; (B) 3.14 m; (C) 4.14 m; (D) 5.14 m; (E) 6.14 m. (3) How many destructive interference points will she encounter? (A) 1; (B) 2; (C) 3; (D) 4; (E) 5.
