- 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?arrow_forwardTwo loudspeakers, placed on opposite walls of a 10m long room, emit pure sine waves at f= 170 Hz coherently. If we were exactly in the middle of the room, where the interference of waves is constructive, what is the shortest distance we should travel towards one of the speakers so that the waves cancel out completely?" Assume that the speed of sound at air is 340 m/s.arrow_forwardTwo out of phase loudspeakers are some distance apart. A person stands 5.30 m from one speaker and 2.60 m from the other. What is the third lowest frequency at which constructive interference will occur? The speed of sound in air is 338 m/s.arrow_forward
- Two loudspeakers placed 6 m apart are driven in phase by an audio oscillator whose frequency range is 950 Hz to 1350 Hz. A point P is located 5 m from one loudspeaker and 3.5 m from the other. The speed of sound is 350 m/s. The frequency produced by the oscillator, for which constructive interference of sound occurs at point P, is closest to what?arrow_forwardSuppose that the separation between two speakers A and B is 6.90 m and the speakers are vibrating in-phase. They are playing identical 135-Hz tones and the speed of sound is 343 m/s. An observer is seated at a position directly facing speaker B in such a way that his line of sight extending to B is perpendicular to the imaginary line between A and B. What is the largest possible distance between speaker B and the observer, such that he observes destructive interference?arrow_forwardTwo identical sources of sound, both emitting waves of equal amplitude and a frequency of 2000Hz, are 80cm apart. A microphone is located on the center line a distance of 2.0m away. What is(a)JK at what angle theta should one observe the first maximum on each side of the center line(b) in radians and(c) in degrees? Assume the speed of sound to be 350 m/sarrow_forward
- At a location that is 3.00 m from wave source A and 4.20 m from wave source B, constructive interference occurs. Source A and source B are coherent and in phase. What is the maximum wavelength of the waves?arrow_forwardTwo speakers, A and B, are in phase and 2 meters apart on the x-axis. Theyare both emitting a pure tone with a wavelength of 2 meters. How fardirectly in front of speaker B (walking in the y-direction) must you go untilthe first time you experience total destructive interference?arrow_forwardA riverside warehouse has several small doors facing the river. Two of these doors are open as shown in Figure P27.17. The walls of the warehouse are lined with sound-absorbing material. Two people stand at a distance L = 150 in from the wall with the open doors. Person A stands along a line passing through the midpoint between the open doors, and person B stands a distance y = 20 m to his side. A boat o the river sounds its horn. To person A, the sound is loud and clear. To person B, the sound is barely audible. The principal wavelength of the sound waves is 5.00 m. Assuming person B is at the position of the first minimum, determine the distance d between the doors, center to center.arrow_forward
- The figure shows a loudspeaker A and point C, where a listener is positioned. [AC| = 4.50 m and the angle 8 = 42 °. A second loudspeaker B is located somewhere to the left of A. Both speakers vibrate in phase and are playing a 69.0 Hz tone. The speed of sound is 343 m/s. Excluding point (A), what is the fourth closest to speaker A that speaker B can be located, so that the listener hears maximum sound?arrow_forwardThe following two lists give the diameters and sound frequencies for three loudspeakers. Pair each diameter with a frequency, so that the diffraction angle is the same for each of the speakers, and then find the common diffraction angle. Take the speed of sound to be 343 m/s. Diameter, D Frequency, f 0.07 m 5 kHz 0.35 m 10 kHz 0.14 m 2 kHz θ = Numberarrow_forwardMicrowaves of wavelength 5.50 cm enter a long, narrow window in a building that is otherwise essentially opaque to the incoming waves. If the window is 38.0 cm wide, what is the distance from the central maximum to the first-order minimum along a wall 6.35 m from the window? cmarrow_forward
