Two speakers, emitting identical sound waves of wavelength 0.9 m in phase with each other, and an observer are located as shown in the figure below. (Let x = 5.0 m, and y = 6.0 m.)

(a) At the observer's location, what is the path difference for waves from the two speakers?

____________ m

(b) Will the sound waves interfere constructively or destructively at the observer's location?

constructive or

destructive

(c) Suppose the observer now increases her distance from the speakers to 27.6 m, staying directly in front of the same speaker as initially. What is the path difference for waves from the two speakers?

_______ m

Will the sound waves interfere constructively or destructively at the observer's location?

constructive or

destructive
