Question 8 (15 Points)
Two identical loudspeakers are placed side-by-side two meters
apart. They emit sound at 1800Hz into a room where the speed of
sound is 340 m/s.
(a) Calculate the path difference for sound traveling from each
speaker to a point 4.0 m directly in front of one of the speakers.
(5 points)
(b) Calculate the number of wavelengths that would fit into this
path difference. Round your result to one decimal place. (6
points)
(c) Does this point exhibit maximum constructive interference,
perfect destructive interference, or somewhere in between? (4
points)

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.

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...

Two in-phase loudspeakers, which emit sound in all directions, are sitting side by side. One of them is moved sideways by 6.0 m, then forward by 6.0 m. Afterward, constructive interference is observed 1/4 and 3/4 of the distance between the speakers along the line that joins them. Part A What is the maximum possible wavelength of the sound waves?
Two in-phase loudspeakers, which emit sound in all directions, are sitting side by side.
Two in-phase loudspeakers, which emit sound in all directions, are sitting side by side. One of them is moved sideways by 2.0 m, then forward by 8.0 m. Afterward, constructive interference is observed 1/4 1/2, and 3/4 the distance between the speakers along the line that joins them, and at no other positions along this line. What is the maximum possible wavelength of the sound waves?

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.
