Two small loudspeakers emit pure sinusoidal waves with frequency-independent amplitude that are in phase.
| a ) At the frequencies 0.63 kHz, 1.91 kHz, and 3.19 kHz we have constructive interference at point P. |
| b) | At the frequencies 1.27 kHz, 2.55 kHz, and 3.82 kHz the sound at point P is very soft. |
| c) | At the frequencies 1.27 kHz, 2.55 kHz, and 3.82 kHz the sound at point P is loud. |
| d) | The intensity of the sound at point P does not depend on the frequency. |
e)  |
Since the distances from the two speakers to point P are different, we always have destructive interference. |
Homework Answers

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...

32. Two loudspeakers, A and B , are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m to the right of speaker A. Consider point Q along the extension of the line connecting the speakers, 1.00 m to the right of speaker B. Both speak- ers emit sound waves that travel directly from the speaker to point Q. (see figure) (a) What is the lowest frequency for which constructive interference occurs at point...

Two loudspeakers, 1.3 m apart, emit sound waves with the same frequency along the positive x-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.

Two in-phase loudspeakers are 3.00 m apart. They emit sound with a frequency of 490 Hz. A microphone is placed half-way between the speakers and then moved along the line joining the two speakers until the first point of constructive interference is found. At what distance from that midpoint is that first point? The speed of sound in air is 343 m/s. Please work with this example. This question was asked on chegg and was not answered using the numeric...

Interference with Loudspeakers Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves OUT of phase. The frequency of the waves emitted by each speaker is 172 Hz. You are 8.00 m from speaker A. Take the speed of sound in air to be 344 m/s.(Hint: out of phase means their phase constants differ by pi ) (a) What is the closest you can be to speaker B and be at a point of maximum...

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)...
