Wave Basics — Quiz

Test your understanding of wave basics with 5 practice questions.

Practice Questions

Question 1

A wave is traveling through a medium. If the wave's amplitude is doubled, how does this affect the energy transported by the wave, assuming all other factors remain constant?

Question 2

A wave has a frequency of $600 \text{ Hz}$ and a speed of $300 \text{ m/s}$ in a particular medium. If this wave then enters a new medium where its speed becomes $450 \text{ m/s}$ while its frequency remains constant, what is the new wavelength of the wave?

Question 3

Which of the following statements most accurately describes the fundamental difference in how transverse and longitudinal waves transfer energy through a medium?

Question 4

A wave is described by the equation $y(x,t) = A \cos(kx - \omega t + \phi)$. Which parameter in this equation represents the angular frequency of the wave?

Question 5

Consider a wave traveling in a string. If the tension in the string is quadrupled, how does this affect the speed of the wave, assuming the linear mass density remains constant?
