Sound of frequency 372.7 hz propagates in phase from two loudspeakers; the speed of sound in air is 343.5 m/s. the first loudspeaker is at the origin, and the second is at 8.8m·(j is the unit vector in the y-direction) a person starts on the x-axis at a very long distance from the loudspeakers and walks directly towards the loudspeaker at the origin. how far is the person from the origin the second time they encounter a loud sound (constructive interference)?
