Question

Suppose that the separation between speakers A and B is 5.00 m and the speakers are vibrating in phase. They are playing identical 125-Hz tones, and the speed of sound is 343 m/s. What is the largest possible distance between speaker B and the observer at C, such that he observes destructive interference?

Answer 1

The largest possible distance between speaker B and the observer at C is 1.37 m.

Largest possible distance between the observer and speaker B

The largest possible distance between speaker B and the observer at C occurs when the difference in travel distances is just one half wavelength.

λ = v/f

λ = (343)/125

λ = 2.744

¹/₂λ = ¹/₂(2.744) = 1.37 m

Thus, the largest possible distance between speaker B and the observer at C is 1.37 m.
