Two speakers, A and B, are 4.00 m apart and are emitting identical in-phase sound waves. The speed of sound in air is 340 m/s. Consider a line which is the perpendicular bisector of the line connecting the two speakers. The first interference maximum occurs at ±25.15 o from this line. (a) What is the frequency of the sound emitted? (b) Find the rest of the angles where constructive and destructive interference occur. (c) If the speakers are aboard a...
Two loudspeakers, labeled A and B, emnit sound waves in every direction. Both speakers emit sound with the same wavelength, and they are in phase (they emit peaks of the sound wave at the same time). The location labeled C is a location of constructive interference, and the location labeled D is a location of destructive interference. The distances from the loudspeakers to the locations are as indicated. (Picture may not be to scale!!) (a) What is the wavelength of...
2. The speed of sound in air is 345 m/s. (7 pts) (a) Speakers A and B operate from the same transmitter and therefore emit sound waves in phase. The frequency of the sound waves is 115 Hz. Speaker B is 6.00 m to the right of speaker A and point P is 13.5 m to the right of speaker B, as shown in the sketch. Is the interference at P constructive or destructive? 6m . 13.5m Ans. constructive
Two speakers are separated by two meters in a plane. They are in-phase. They project 891 Hz sound waves. The speed of sound is 343 m/s. Consider the point 5.0 m in front of one of the speakers, perpendicular to the plane of the speakers. At this point, is there maximum constructive interference, perfect destructive interference, or something in between?
Two speakers, which are separated by a distance d,
produce sound waves with the same amplitude, phase and frequency.
The frequency of the sound is 570 Hz. You stand a distance of 3.50
m directly in front of the left speaker, on the dashed line shown
in the diagram. Assume the speed of sound to be 340 m/s. What is
the smallest possible value of d so that you hear no sound
because of destructive interference?
Two speakers are completely out of phase, each emitting a sound that has a wavelength of 2.0 m. Speaker A is at the origin, while Speaker B is at a position of 11 m along the x-axis. Is the point P at 4.0 m on the x-axis a point of completely constructive interference, completely destructive interference or neither? у P B completely constructive interference completely destructive interference neither

Two speakers spaced a distance 1.8 m apart emit coherent sound waves at a frequency of 547 Hz in all directions. The waves start out in phase with each other. A listener walks in a circle of radius one meter centered on the midpoint of the two speakers. At how many points does the listener observe destructive interference? The listener and the speakers are all in the same horizontal plane and the speed of sound is 340 m/s.
Question 2 A pair of in-phase speakers are placed next to each other 0.60 m apart. You stand directly in front of one of the speakers, 1 m from the speaker. a. What is the lowest frequency that will produce constructive interference at your location? b. What is the lowest frequency that will produce destructive interference at your location? Hint: When it comes to the lowest, what is the value of n 5+5 !! =
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.
