(4) How far must the listener walk to reach the first destructive interference? (A) 0; (B) 1.37 m; (C) 1.87 m; (D) 2.37 m; (E) 2.87 m.

(6) How many destructive interference points does the listener encounter?

Two identical loudspeakers 10.0 m apart are driven by the same oscillator with a frequency of f = 21.5 Hz (Fig. P17.6) in an area where the speed of sound is 344 m/s. (a) Show that a receiver at point A records a minimum in sound intensity from the two speakers. (b) If the receiver is moved in the plane of the speakers, show that the path it should take so that the intensity remains at a minimum is along the hyperbola 9x2 16y2 = 144 (shown in red-brown in Fig. P17.6). (c) Can the receiver remain at a minimum and move very far away from the two sources? If so, determine the limiting form of the path it must take. If not, explain how far it can go. Figure P17.6
Two sinusoidal waves with identical wavelengths and amplitudes travel in opposite directions along a string producing a standing wave. The linear mass density of the string is =0.075 kg/m and the tension in the string is FT=5.00 N. The time interval between instances of total destructive interference is t=0.13 s. What is the wavelength of the waves?
The acoustic impedance of water is Zwater = 1440000 kg/(m2 s), and that of bone is Zbone = 7800000 kg/(m2 s). What proportion of the energy of a sound wave propagating in water will be reflected at the water-bone boundary?
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?
Two 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.

One string of a certain musical instrument is 79.0 cm long and has a mass of 8.73 g. It is being played in a room where the speed of sound is 344 m/s. To what tension must you adjust the string so that, when vibrating in its second overtone, it produces sound of wavelength 0.763 mm? (Assume that the breaking stress of the wire is very large and isn’t exceeded.) Express your answer in newtons. What frequency sound does this string produce in its fundamental mode of vibration? Express your answer in hertzes.
