In a transverse wave, the distance between two consecutive crests is called the $\mathrm{wavelength}$. If a wave is shown with a total length of $6 m$ and the wavelength is $2 m$, how many complete wavelengths are present in the image?

When a transverse wave travels along a string, in what direction does each individual part of the string move relative to the direction of wave propagation?

Which of the following factors directly affect the velocity $v$ of a transverse wave on a stretched string?

Which of the following best describes the main difference between transverse and longitudinal waves?

A transverse wave has a frequency of $500\mathrm{Hz}$ and is traveling at a speed of $200m/s$. What is its wavelength?

Which type of earthquake wave travels fastest?

Given four transverse waves on identical strings, which wave will produce the highest pitch?

Which of the following best describes the typical velocity of $S$ (secondary) waves as they travel through Earth's crust?

A transverse wave has a frequency of $50\mathrm{Hz}$ and a wavelength of $10m$. What is the speed of the wave?

Which of the following equations correctly gives the velocity of a transverse wave on a stretched string in terms of the string's tension $T$ and mass per unit length $\mu$?

If the speed of a transverse wave doubles while the wavelength remains the same, what happens to the frequency of the wave? $v=f\lambda$

Which type of wave displaces the particles of its medium in the same direction as the wave's propagation?
