two loudspeakers are placed at either end of a gym bothpointingtowards the center. the speakers emit 266-Hz that is inphase soundthat experiences constructive interference.
(a) does the required distance increase, decrease or stay thesameif the frequency of the speakers is lowered?
(b) calculate the distance to the intersection of thedestructiveinterference. if the frequency emmited by the speakersis loweredto 238Hz?

Two loudspeakers are placed at either end of a gymnasium,bothpointing
toward the center of the gym and equidistant from it. Thespeakersemit 256-Hz sound
that is in phase. An observer at the center of the gymexperiencesconstructive
interference. Does the required distance increase, decrease, orstaythe same if the
frequency of the speakers is lowered? (b) Calculate the distancetothe first position of
destructive interference if the frequency emitted by the speakersislowered to 242 Hz.

Two loudspeakers, A and B (Fig. 16.41), are driven by the
same amplifier and emit sinusoidal waves in phase. Speaker Bis
2.00 m to the right of speaker A. The frequency of the soundwaves
produced by the loudspeakers is 206 Hz. Consider point Pbetween
the speakers and along the line connecting them, a distance x tothe
right of speaker A. Both speakers emit sound waves thattravel
directly from the speaker to point P. a) For what values of xwill
destructive interference occur at point P? b) For what values ofx
will constructive interference occur at point P? c)Interference
effects like those in parts (a) and (b) are almost never a factorin lis-
tening to home stereo equipment. Why not?
