18. Waves & Sound

In the context of the velocity of transverse waves, what are the low points of a transverse wave called?

Which of the following is a similarity between transverse and longitudinal waves?

The string in FIGURE P16.59 has linear density μ. Find an expression in terms of M, μ, and θ for the speed of waves on the string.

What is the speed of a transverse wave with a frequency of $2\mathrm{Hz}$ and a wavelength of $87m$?

As the frequency $f$ of a transverse wave increases, what happens to its wavelength $\lambda$ if the wave speed $v$ remains constant?

A rope with length 2.50 m and mass 0.10 kg is stretched and pulled to create transverse waves of frequency 40.0 Hz and wavelength of 0.750 m. How much tension is exerted on the rope?

The wave speed on a string under tension is 200 m/s. What is the speed if the tension is halved?

A 2 m long string is arranged as shown in the figure below. If the mass of the string is 0.5 kg, what would the frequency be of a wave with a 2 cm wavelength?

A ski gondola [pronounced gon–do–la] is connected to the top of a hill by a steel cable of length 710 m and diameter 1.5 cm. As the gondola comes to the end of its run, it bumps into the terminal and sends a transverse wave pulse along the cable. It is observed that it took 17 s for the pulse to return. What is the tension in the cable?
