Two speakers in a row emit sound waves that oscillate at 663 Hz and travel at 343 m/s in the horizontal direction as shown in the figure below. (Note that the speakers are drawn displaced from each other for clarity. They are, in fact, in line with each other so their sound waves overlap as they travel.) If the speakers are in-phase or coherent, what is the smallest distance d between them for which the interference of the sound waves is perfectly destructive? If the speakers are in-phase or coherent, what is the smallest non- zero distance d between them for which the interference of the sound waves is perfectly constructive? If the speakers are exactly 180° out-of-phase or incoherent, what is the smallest non-zero distance d between them for which the interference of the sound waves is perfectly destructive? If the speakers are exactly 180° out-of-phase or incoherent, what is the smallest distance d between them for which the interference of the sound waves is perfectly constructive?
