Two identical speakers are spaced 12 m apart, aimed toward each other. They each play a 171.5 Hz tone with the same phase constant. A. If you stand at the center point between the speakers, the result of superposition of the sound waves from the speakers is constructive inteference. Explain. B. How far must you move from the center toward one of the speakers in m to reach the next point of destructive interference?

Two loudspeakers, 5.0 m apart and facing each other, play identical sounds of the same frequency. You stand halfway between them, where there is a maximum of sound intensity. Moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.35 m . Assume the speed of sound is 340 m/s. Part A: What is the frequency of the sound? Express your answer with the appropriate units. Part B: If the...

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...
