Chapter 2: Q33E (page 499)

Suppose that the left-traveling pulse in Exercise 15.32 is below the level of the unstretched string instead of above it. Make the same sketches that you did in that exercise

Short Answer

Expert verified

The sketches are shown below.

Step by step solution

01

Identification of the given data

The given data can be listed below as,

  • The given times are, \(t = 0.250\;{\rm{s}},\,t = 0.500\;{\rm{s}},\,t = 0.750\;{\rm{s}},\,t = 1.000\;{\rm{s}},\,t = 1.250\;{\rm{s}}\).
02

Significance of the principle of superposition

According to the superposition principle, the total disturbance caused by two or more waves overlapping in space equals the algebraic sum of the individual disturbances.

03

Determination of the sketches

During their overlap, the pulses interfere with one another, but once they have completely gone through one another, they take on their original shape.

The figure below shows the string's shape at each designated period,

A violinist is tuning her instrument to concert A (440 Hz). She plays the note while listening to an electronically generated tone of exactly that frequency and hears a beat frequency of 3 Hz, which increases to 4 Hzwhen she tightens her violin string slightly. (a) What was the frequency of the note played by her violin when she heard the3 Hz beats? (b) To get her violin perfectly tuned to concert A, should she tighten or loosen her string from what it was when she heard the 3 Hzbeats?

Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 12.0 m to the right of speaker A. The frequency of the waves emitted by each speaker is 688 Hz. You are standing between the speakers, along the line connecting them, and are at a point of constructive interference. How far must you walk toward speaker B to move to a point of destructive interference?

In most modern wind instruments the pitch is changed by

using keys or valves to change the length of the vibrating air column.

The bugle, however, has no valves or keys, yet it can play many notes. How might this be possible? Are there restrictions on what notes a bugle can play?

A loud factory machine produces sound having a displacement amplitude of 1.00 μ-m, but the frequency of this sound can be adjusted. In order to prevent ear damage to the workers, the maxi mum pressure amplitude of the sound waves is limited to 10.0 Pa. Under the conditions of this factory, the bulk modulus of air is 1.42 x 105 Pa. What is the highest-frequency sound to which this machine can be adjusted without exceeding the prescribed limit? Is this frequency audible to the workers?

In Example 16.18 (Section 16.8), suppose the police car is moving away from the warehouse at 20  m/s . What frequency does the driver of the police car hear reflected from the warehouse?
