**Interference and Sound Intensity Problem****Problem Statement:**Two small identical speakers are connected (in phase) to the same source. The speakers are 3 meters apart and at ear level. An observer stands 4 meters in front of one speaker (at point X) as shown. Determine at which wavelength the sound the observer hears will be least intense.**Diagram Explanation:**- There are two speakers labeled as "Speaker 1" and "Speaker 2".- The speakers are 3 meters apart.- An observer is positioned at point X, which is 4 meters directly ahead of "Speaker 2".**Possible Wavelengths:**- (a) 1 meter- (b) 2 meters- (c) 3 meters- (d) 4 meters- (e) 5 meters

Speakers A and B are 100 m apart and send out coherent sound waves with frequency of f = 200 Hz. Alice is standing at the center of the line that connects the two speakers.

Solve Apo = 0 Submit ✓ Correct Because constructive interference is observed when Ar = 0, that is, when the listener is equidistant from the sources, the speakers must be sources of in-phase waves.

In the figure, sound waves A and B, both of wavelength 12.0 m, are initially in phase and traveling rightward. They each reflect several times but end up traveling in their original direction.

A loudspeaker is placed between two observers who are 110 m apart, along the line connecting them. If observer 1 records a sound level of 80 dB, what is the sound level observer 2 records? Observer 2 is 10 m from the speaker. State your answer to the nearest dB.
Sound with a 29 cm wavelength travels rightward from a source and through a tube that consists of a straight portion and a half-circle. Part of the soundwave travels through the circle and rejoins the the rest of the wave which goes directly through the straight portion. This rejoining results in interference. What is the smallest radius r (in cm) that results in an intensity minimum at the detector. The maximum destructive interference will occur when the difference in the distance travelled by the two waves is 1/2 of a wavelength. To solve this problem express the difference in the distance travelled by the two waves as a function of r and set this amount equal to 1/2 of a wavelength.

Consider the speaker set-up in the previous question. Each speaker emits a frequency of 6.6·102 Hz in phase with the other. The listener is seated directly in front of one speaker, 1.6 m away. The speakers are 2.4 m away from each other. How many extra wavelengths are needed for sound to get from speaker 2 to the listener? Take the speed of sound in air to be 3.4·102 m/s.
