Two identical speakers are continuously emitting sound waves
uniformly in all directions at 440 Hz with amplitude A. At time t =
0, air particles are maximally displaced at the locations of each
of the speakers. The speed of sound is 344 m/s. Point P is a
distance of r1 = 3.13 m away from speaker 1 and r2 = 4.30 m from
speaker 2. A) At time t = 2.27 ms: i. What is the displacement of
an air particle at point P due to speaker 1? ii. What is the
displacement of an air particle at point P due to speaker 2? iii.
What is the net displacement of an air particle at point P? B) What
is the phase difference between the two sound waves at point P? C)
What is the path-length difference from the two speakers at point
P, expressed as a factor of wavelength? D) Is point P a point of
constructive or destructive interference? Explain, using your
answers to parts (A), (B), and (C).
