Chapter 2: Q17DQ (page 538)

A large church has part of the organ in the front of the church and part in the back. A person walking rapidly down the aisle while both segments are playing at once reports that the two segments sound out of tune. Why?

Short Answer

Expert verified

The person will perceive the 2 sources as being out of tune with one another due to the doppler effect.

Step by step solution

01

Explanation

The person is approaching the sound source in the front and will perceive a higher frequency than what is emitted.At the same time, the person is walking away from the sound source in the back and will perceive a lower frequency than what is emitted. This is known as Doppler Effect.
Thus, If both sources are emitting the same frequency, the person will perceive the 2 sources as being out of tune with one another.

The four strings on a violin have different thicknesses but are all under approximately the same tension. Do waves travel faster on the thick strings or the thin strings? Why? How does the fundamental vibration frequency compare for the thick versus the thin strings?

If you stretch a rubber band and pluck it, you hear a (somewhat) musical tone. How does the frequency of this tone change as you stretch the rubber band further? (Try it!) Does this agree with Eq. (15.35) for a string fixed at both ends? Explain.

Longitudinal Waves on a Spring. A long spring such as a SlinkyTMis often used to demonstrate longitudinal waves. (a) Show that if a spring that obeys Hooke’s law has mass m, length L, and force constant k′, the speed of longitudinal waves on the spring is v=Lk'm

(see Section 16.2). (b) Evaluate v for a spring with m = 0.250 kg, L = 2.00 m, and k′ = 1.50 N/m.

(a) A sound source producing 1.00-kHz waves moves toward a stationary listener at one-half the speed of sound. What frequency will the listener hear? (b) Suppose instead that the source is stationary and the listener moves toward the source at one-half the speed of sound. What frequency does the listener hear? How does your answer compare to that in part (a)? Explain on physical grounds why the two answers differ.

You have a stopped pipe of adjustable length close to a taut 62.0-cm, 7.25-g wire under a tension of 4110 N. You want to adjust the length of the pipe so that, when it produces sound at its fundamental frequency, this sound causes the wire to vibrate in its second overtone with very large amplitude. How long should the pipe be?
