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

Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 19 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 29 cm. What is the wavelength of the sound? Express your answer using two significant figures. If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum? Express your answer using two significant...

Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x = 0.500m . If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at x =0.850m . A)What is the frequency of the sound? Assume vsound =340m/s. B)What is the phase difference between the speakers?

Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x = 0.540m . If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at x =0.930m . What is the phase difference between the speakers?

Two small loudspeakers emit sound waves of different frequencies equally in all directions. Speaker A has an output of 1.30 mW, and speaker B has an output of 1.60 mW. Two speakers A and B are represented as points which serve as the centers of concentric circles representing sound waves emanating from the speakers. The concentric circles about speaker A are spaced more closely together than the concentric circles about speaker B. The points lie along a horizontal line, and...
