- You are in a room with two speakers that emit sound in phase. You are 12.0 m from the first speaker and 16.2 m from the second speaker. (The speed of sound in air is 343 m/s.) What is the smallest frequency for which you will measure fully destructive interference? What is the smallest nonzero frequency for which you will measure fully constructive interference?Two speakers, emitting identical sound waves of wavelength 2.0 m in phase with each other, and an observer are located as shown in Fig. (a) At the observer’s location, what is the path difference for waves from the two speakers? (b) Will the sound waves interfere constructively or destructively at the observer’s location—or something in between constructive and destructive? c) Suppose the observer now increases her distance from the closest speaker to 17.0 m, staying directly in front of the same speaker as initially. Answer the questions of parts (a) and (b) for this new situation.In the figure, two loudspeakers, separated by a distance of d; at the position of a listener, who is d, = 3.81 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.) 2.74 m, are in phase. Assume the amplitudes of the sound from the speakers are approximately the same %D di Speakers Listener (a) Number Units (b) Number Units
- Two identical loudspeakers, A and B, are 2.00 m apart. The loudspeakers are driven by the same amplifier and emit 784 Hz sound waves in all directions. Take the speed of sound in air to be 344 m/s. A small microphone is moved out from point B along a line perpendicular to the line connecting A and B (line BC in the figure) At what distances from BB will there be destructive interference?Two speakers connected to the same frequency generator emit a sound with afrequency of 500 Hz. As a person walks around in the room, he finds areas wherethe sound becomes loud and clear and areas where it is more muffled. At one spotwhere the sound is a maximum, the student is 3.2 m from one speaker. What isthe closest possible distance he could be to the other speaker?Two identical point sources are 5.0 cm apart, in phase and vibrating at a frequency of 12 Hz. They produce an interference pattern. A point on the first nodal line is 5 cm from one source and 5.5 cm from the other. Determine thewavelength and the speed of the waves.
- 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. Part C Find v, the speed of the sound waves in air. Express your answer in meters per second to three significant figures. ► View Available Hint(s) v = 351 m/s Submit Previous Answers Review Part D T₂ = Previous Answers Correct How far (r.) from its original location should the speaker be moved for the listener to experience constructive interference for the second time? Express your answer in meters to three significant figures. ► View Available Hint(s) OF IVE ΑΣΦ ? mIn 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. What is the second smallest value (m) of d that puts A and B exactly out of phase with each other after the reflections? A B d 2d |—a—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.

The speakers emit 246 Hz sound that is in phase. An observer at the center of the gym experiences constructive interference. How far toward either speaker must the observer walk to first experience destructive interference?
