Two speakers are located at two neighboring corners of a squareof side length 10.00 m. A listener walks from another corner of thesquare along the side toward the speaker next to her. Assume thatthe two speakers are playing the same 75.0-Hz tone in phase and thesound speed in the air is 343 m/s. (1) How far must she walk toreach 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 toreach 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 destructiveinterference points will she encounter? (A) 1; (B) 2; (C) 3; (D) 4;(E) 5.
