Chapter 18, Problem 18.9OQ
As oppositely moving pulses of the same shape (one upward, one downward) on a string pass through each other, at one particular instant the string shows no displacement from the equilibrium position at any point. What has happened to the energy carried by the pulses at this instant of time? (a) It was used up in producing the previous motion. (b) It is all potential energy. (c) It is all internal energy. (d) It is all kinetic energy. (e) The positive energy of one pulse adds to zero with the negative energy of the other pulse.

Why should one use string that does not stretch when producing standing waves? How would a string that stretched a lot affect the value of the velocity? If a string stretched, would it make the resonant frequency go up or down as compared to a string that did not stretch?
A standing wave on a string fixed at both ends is vibrating at its fourth harmonic. If the length, tension, and linear density are kept constant, what can be said about the wavelength and frequency of the fifth harmonic relative to the fourth harmonic? (a) The wavelength of the fifth harmonic is longer, and its frequency is higher. (b) The wavelength of the fifth harmonic is longer, and its frequency is lower. (c) The wavelength of the fifth harmonic is shorter, and its frequency is higher. (d) The wavelength of the fifth harmonic is shorter, and its frequency is lower.

- A series of pulses, each of amplitude 0.150 m, are sent down a string that is attached to a post at one end. The pulses are reflected at the post and travel back along the string without loss of amplitude. When two waves are present on the same string, the net displacement of a particular element of the string is the sum of the displacements of the individual waves at that point.

- Suppose that there are standing waves in a closed pipe. Which of the following is true regarding the harmonics present? Only even harmonics are present. Only odd harmonics are present.

The rope has mass per unit length m and is under tension F. Without warning, Cousin Throckmorton starts a sinusoidal transverse wave of wavelength l propagating along the rope. The motion of the rope is in a vertical plane. What minimum wave amplitude will make the ant become momentarily weightless?

- An object of mass m can be hung from a rope (with linear mass density = 0.002 kg/m) that passes over a light pulley. The string is connected to a vibrator (which makes the string oscillate with a constant frequency f) and the length of the string between the point where the string is attached to the vibrator and the pulley is L = 2 m. When the mass of the object is m = 25 kg or m = 16 kg, standing waves are observed; however, no standing waves are observed with any other mass between these values, which means that they correspond to consecutive nodes, n and n + 1.a) What is the value of the tension of the string, FT, corresponding to each of the masses?b) In what harmonic does the string vibrate when the mass m = 25 kg is hung?arrow_forwardTwo strings made of the same material (same mass density) and stretched to the same tension (and thus, having the same speed) have a different length. One of the strings is 80-cm long (String A) and the other string is 60 cm (String B). They are vibrated at various frequencies in order to establish standing wave patterns within them.
