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?
Find the path difference for the two waves from the two sources
and use condition for constructive interference to find the
solution as shown below

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...
In the figure, two loudspeakers, separated by a distance of d1 = 2.89 m, are in phase. Assume the amplitudes of the sound from the speakers are approximately the same at the position of a listener, who is d2 = 4.08 m directly in front of one of the speakers. Consider the audible range for normal hearing, 20 Hz to 20 kHz. (a) What is the lowest frequency that gives the minimum signal (destructive interference) at the listener's ear? (b)...
Question 27 7.0 m Two loudspeakers in a 20°C room emit 686 Hz sound waves which travel at 343 m/s. These two speakers are wired oppositely as in ILL and emit equal amplitude sound waves.

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.
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 identical speakers (labeled 1 and 2) are playing a tone with a frequency of 225 Hz, in phase. The centers of the speakers are located 6.00 m apart. Five observers are standing on a line that is 6.00 m in front of the speakers as shown in the figure. Each observer is separated by 1.00 m and Sue is directly in front of speaker 1. Determine which observer or observers will experience constructive interference from the sound emitted by...
Two loudspeakers in a plane are 2.0 m apart and in phase with each other. The speed of sound is 340 m/s. Assume the amplitude of the sound from each speaker is approximately the same at the position of a listener, who is 3.75 m directly in front of one of the speakers. a) (10pts) For what three lowest frequencies will there be a minimum signal (destructive interference)? b) (10pts) For what three lowest frequencies will there be a maximum...
Two speakers, 1 and 2, are set up with their centers 6.00 m apart. Both are playing the same tone of frequency 225 Hz, in phase. Five listeners are standing on a line that is 6.00 m in front of the speakers as shown in the figure. Each listener is separated by 1.00 m and Cal is directly in front of speaker 1. Determine which listener or listeners will experience constructive interference from the sound emitted by the speakers. The...
The diagram below (not drawn to scale) shows a pair of speakers producing sound in phase (at the speakers). The frequency of the sound is 340 Hz. All distances are given in the table below. all angles that appear to be right angles are right angles. Is the interference at point B constructive or destructive? Is the interference at point C constructive or destructive? Is the interference at point D constructive or destructive?
This experiment requires two speakers that can be separated by some distance (try 1-2 meters). Try playing a single frequency using a tone generator and walk side to side in front of the speakers. Can you hear where there is constructive and destructive interference? Can you predict where the sound will get louder or quieter? What changes when you change the frequency?
