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.

One end of a horizontal rope is attached to a prong of another end passes over a pulley and supports a 1.50-kg mass. The linear mass density of the rope is 0.0480 kg/m. (a) What is the speed of a transverse wave on the rope? (b) What is the wavelength? (c) How would you answer to parts (a) and (b) change if the mass were increased to 3.00 kg?

The motors that drive airplane propellers are, in some cases, tuned by using beats. The whirring motor produces a sound wave having the same frequency as the propeller. (a) If one single-bladed propeller is turning at 575rpm and you hear 2Hz beats when you run the second propeller, what are the two possible frequencies (in rpm) of the second propeller? (b) Suppose you increase the speed of the second propeller slightly and find that the beat frequency changes to 2.1Hz. In part (a), which of the two answers was the correct one for the frequency of the second single-bladed propeller? How do you know?

Is it possible to have a longitudinal wave on a stretched string? Why or why not? Is it possible to have a transverse wave on a steel rod? Again, why or why not? If your answer is yes in either case, explain how you would create such a wave.

The longest pipe found in most medium-size pipe organs is 4.88 m (16 ft) long. What is the frequency of the note corresponding to the fundamental mode if the pipe is (a) open at both ends, (b) open at one end and closed at the other?

You live on a busy street, but as a music lover, you want to reduce the traffic noise. (a) If you install special sound reflecting windows that reduce the sound intensity level (in dB) by 30 dB, by what fraction have you lowered the sound intensity(W/m2)?(b) If, instead, you reduce the intensity by half, what change (in dB) do you make in the sound intensity level?
