Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. The frequency of the waves emitted by each speaker is 708 Hz. You are standing between the speakers, along the line connecting them and are at a point of constructive interference. How far must you walk toward speaker B to move to reach the first point of destructive interference? Take the speed of sound to be 344 m/s. Express your answer in meters.

In the figure, two loudspeakers, separated by a distance of d1 = 2.63 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 = 4.34 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) What is the lowest frequency that gives the maximum signal (constructive interference) at the listener's ear? (Take the speed of sound to be 343 m/s.)
Two identical loudspeakers 2.0 m apart are emitting 1800 Hz sound waves into a room where the speed of sound is 340 m/s. Is the point 4.0 m directlyin front of one of the speakers, perpendicular to the line joining the speakers, a point of maximum constructive interference, perfect destructive interference, or something in between?
A point source broadcasts sound into a uniform medium. If the intensity at a distance r is I, by what factor will the intensity change when the distance changes to 1.8r?
A student connects a speaker to the signal generator and sets the frequency to 500 Hz. He notices that the sound coming from a resonance tube gets noticeably louder at the lengths 85.5 cm and 119.8 cm but at not any lengths between. Using these values, calculate ΔL. Using ΔL, calculate wavelength λ. Finally, calculate the speed of sound.

Two small speakers, 0.610 m apart, are facing in the same direction. They are driven by one 685 Hz oscillator and therefore emit identical sound waves in phase with one another at the respective points of origin. (The speed of sound waves in air is 343 m/s.) Two speakers are side by side, with one speaker on the left and one on the right. The speakers are separated by a distance d and emit sound waves in the same direction. A man stands directly in front of the speaker on the right but a distance x away from the right speaker.
