Question:
In Problem 59, suppose the observer walks toward one speaker with a speed of 1.35 m/s.
(a) What frequency does the observer hear from each speaker?.
(b) What beat frequency does the observer hear?
(c) How far must the observer walk to go from one point of constructive interference to the next?
(d) How many times per second does the observer hear maximum loudness from the speakers? Compare your result with the beat frequency from part (b).
In Problem 59
Two loudspeakers are placed at either end of a gymnasium, both pointing toward the center of the gym and equidistant from it. The speakers emit 266-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?
Step by Step Answer:
Picture the Problem A person walks between two loudspeakers at either end of a gymnasium The speakers emit 266Hz sound that is in phase Strategy Use Equation 149 to calculate the Dopplershifted frequency the moving observer hears from each speaker Use the plus sign for the speaker ...View the full answer
