(numbers 20-21) Two speakers emit the same pure tone (sound of a single frequency) and are in phase.

20. An observer begins at the center point between the speakers and slowly moves toward one of the
speakers. The second very quiet spot encountered (completely destructive interference) is 1.5 m from
the center. What is the wavelength of the sound?
a) 1.0 m
b) 1.5 m
c) 2.0 m
d) 2.5 m
e) 3.0 m
21. If the distance between the speakers is 5.0 m, what is the shortest distance from either speaker
where a loud spot (completely constructive interference) is found?
a) 0.5 m
b) 1.0 m
c) 1.5 m
d) 2.0 m
e) 2.5 m

Two loudspeakers, 1.1 mm apart, emit sound waves with the same frequency along the positive xx-axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency? Assume room temperature of 20∘C∘C. Express your answer with the appropriate units. please write the answer neatly, another post similar to this one was difficult...

Two speakers face each other, and they each emit a sound of wavelength (lambda). One speaker is 180 (degrees) out of phase with respect to the other. If we separate the speakers by a distance1.5 (lambda),how far from the left-most speaker should we place a microphone in order to pick up the loudest sound? Ignore reflections from nearby surfaces. Select all that apply. 3/4 lambda 0 lambda 1/2 lambda 1/4 lambda 1 lambda
