Question 3 J00品05-Interfer...ஆNYC-Midte...XNYC-Pr... ✓+NYC-Probl...Assignment 5- InterferenceThis assignment is meant for practice and will not be collected or marked.Question 1:Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximumsound intensity when speaker 2 is at the origin and speaker 1 is at x=0.510 m. If speaker 1 is slowly movedforward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 isat x = 0.910 m.a) What is the frequency of the sound? Assume Vsound =340 m/s.b) What is the phase difference between the speakers?Question 2:You are standing 2.5 m directly in front of one of the two loudspeakersshown in the figure. They are 3.0 m apart and both are playing a 687 Hztone in phase. As you begin to walk directly away from the speaker, atwhat distance from the speaker do you hear the next minimum soundintensity?Answers: a) 850 Hz b) -1.73 rad2.5 m3.0 mWalkAnswers: 2.98 mQuestion 3:Two loudspeakers in a plane, 6.0 m apart, are playing the same frequency. If you stand 13.0 m in front ofthe plane of the speakers, centered between them, you hear a sound of maximum intensity. As you walkparallel to the plane of the speakers, staying 13.0 m in front of them, you first hear a minimum of soundintensity when you are directly in front of one of the speakers. What is the frequency of the sound?Assume a sound speed of 340 m/s.Answers: 129 HzQuestion 4:A speaker fixed to a moving platform moves toward a wall, emitting a steady sound with a frequency of245 Hz. A person on the platform right next to the speaker detects the sound waves reflected off the walland those emitted by the speaker. How fast should the platform move, vp, for the person to detect a beafrequency of 2.00 Hz? Take the speed of sound to be 344 m/s.Answers: 1.40 m/sPHY-NYCХBLI

Two loudspeakers in a plane, 6.0 m apart, are playing the same frequency. If you stand 13.0 m in front of the plane of the speakers, centered between them, you hear a sound of maximum intensity. As you walk parallel to the plane of the speakers, staying 13.0 m in front of them, you first hear a minimum of sound intensity when you are directly in front of one of the speakers. What is the frequency of the sound? Assume a sound speed of 340 m/s.
