distance from speaker = r1 = 6 m
distance from identical speaker = r2 = 8m
for constructive interference path difference = r2 - r1 = n * lamda
8-6 = 1* lamda
wavelength = lamda = 2 m

1. (10 points) Two identical speakers are continuously emitting sound waves uniformly in all directions at 440 Hz. The speed of sound is 344 m/s. Point P is a distance of r = 3.13 m away from speaker 1 and r2 = 4.30m from speaker 2: i. What is the phase difference between the waves at Point P? ii. Is this a point of constructive interference, destructive interference, or something in between? Explain.

Two identical speakers (labeled 1 and 2) are playing a tone with a frequency of 225 Hz, in phase. The centers of the speakers are located 6.00 m apart. Five observers are standing on a line that is 6.00 m in front of the speakers as shown in the figure. Each observer is separated by 1.00 m and Sue is directly in front of speaker 1. Determine which observer or observers will experience constructive interference from the sound emitted by...
