Two loudspeakers, A and B (Fig. ), are driven by thesame amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 mto the right of speaker A. Consider point Q along the extension ofthe line connecting the speakers, 1.00 m to the right of speaker B.Both speakers emit sound waves that travel directly from the speaker topoint Q. What is the lowest frequency for which (a) constructive interferenceoccurs at point Q; (b) destructive interference occurs at point Q?
The shortest distance between a sound source (S,) and a reflecting wall is 25 m. The sound is reflected at an angle of a, = 45° to
a listener (L,).
(a) What is the shortest distance between the sound source and the listener, (x1)?
(b) The sound is also reflected to another listener (L2) at an angle of a2= 80°. What is the length of the reflector between the two

What is the displacementamplitude?arrow_forwardOne clue used by your brain to determine the direction of a source of sound is the time delay t between the arrival of the sound at the ear closer to the source and the arrival at the farther ear.Assume that the source is distant so that a wavefront from it is approximately planar when it reaches you, and let D represent the separation between your ears. (a) If the source is located at angle u in front of you , what is in terms of D and the speed of sound v in air? (b) If you are submerged in water and the sound source is directly to your right, what is t in terms of D and the speed of sound vw in water?
