Two pulses are moving in opposite directions at \(1.0\;{{{\rm{cm}}} \mathord{\left/ {\vphantom {{{\rm{cm}}} {\rm{s}}}} \right. \\} {\rm{s}}}\) on a taut string, as shown in Fig. E15.34. Each square is \(1.0\;{\rm{cm}}\). Sketch the shape of the string at the end of

(a) \(6.0\;{\rm{s}}\);

(b) \(7.0\;{\rm{s}}\);

(c) \(8.0\;{\rm{s}}\)

Short Answer

The sketch is shown below.

Step by step solution

01

Identification of the given data

The given data can be listed below as,

  • The speed of pulses is, \(1.0\;{{{\rm{cm}}} \mathord{\left/ {\vphantom {{{\rm{cm}}} {\rm{s}}}} \right. \\} {\rm{s}}}\).
  • The given time is, \(6.0\;{\rm{s}}\).
02

Significance of the principle of superposition

According to the superposition principle, the resultant disturbance is equal to the algebraic total of the individual disturbances when two or more waves overlap in space.

03

Determination of the shape of the string at 6 s

When the pulses overlap, they interfere, but once they have completely passed through one another, they take on their original shape again.

The figure below shows the string's shape at \(6.0\;{\rm{s}}\) designated period,

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?

A baby’s mouth is 30 cm from her father’s ear and 1.50 m from her mother’s ear. What is the difference between the sound intensity levels heard by the father and by the mother?

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.

A light wire is tightly stretched with tension F. Transverse traveling waves of amplitude A and wavelength A₁carry average power Pavg = 0.400 W. If the wavelength of the waves is doubled, so A₂= 2A₁, while the tension F and amplitude A are not altered, what then is the average power Pav,2 carried by the waves?

A 75.0-cm-long wire of mass 5.625 g is tied at both ends and adjusted to a tension of 35.0 N. When it is vibrating in its second overtone, find (a) the frequency and wavelength at which it is vibrating and (b) the frequency and wavelength of the sound waves it is producing.
