compressions rarefactions

Allison wants to calculate the speed of a sound wave. Which formula should she use? distance traveled / amplitude number of wavelengths / amplitude number of wavelengths / time distance traveled / time

distance traveled / time

Sound waves and some earthquake waves [-A-] are waves. Ocean, light, and other earthquake waves are [-B-] waves.

A longitudinal B transverse

A wave is traveling through X. What can be known about X? It is empty space. It is any medium. It is a solid. It is a liquid.

It is any medium

Geneva says that the only thing that is needed for people to hear the sounds around us is a vibrating object. Do you agree with her? Explain your answer.

No, I do not agree with her. In order for sounds to be heard, the sound wave produced by a vibrating object needs to travel from the vibrating object to the ear through a medium. [Sample Response]

Which statement correctly compares sound and earthquake waves? Sound waves and all earthquake waves have compressions and rarefactions. Sound waves and all earthquakes waves have crests and troughs. Sound waves and some earthquake waves have compressions and rarefactions. Sound waves have crests and troughs and all earthquake waves have compressions and rarefactions.

Sound waves and some earthquake waves have compressions and rarefactions.

Which statement correctly compares sound and light waves? Both light and sound waves need matter to carry energy from one place to another. Neither light nor sound waves need matter to carry energy from one place to another. Light waves carry energy parallel to the motion of the wave, while sound waves carry energy perpendicular to it. Sound waves carry energy parallel to the motion of the wave, while light waves carry energy perpendicular to it.

Sound waves carry energy parallel to the motion of the wave, while light waves carry energy perpendicular to it.

In which of these scenarios would the sound of the drumstick hitting the metal bar get to you in the least amount of time? Explain your answer.

The sound of the drumstick hitting the metal bar will get to me in a shorter amount of time in Scenario 1. The sound wave will travel faster in the metal bar than through the air because the speed of sound waves in solids is faster than it is in gases. [Sample Response]

Why do waves move faster at higher temperatures and in a solid phase? There is more energy and the particles are farther apart. There is less energy and the particles are closer together. There is less energy and the particles are farther apart. There is more energy and the particles are closer together.

There is more energy and the particles are closer together

Yulia observed a sound wave moving through a solid medium at four different temperatures, and she recorded observations about each one in the chart. Which correctly ranks, from fastest to slowest, the time it will take one wavelength to pass a certain point? Wave X → Wave Y → Wave W → Wave Z Wave Z → Wave W → Wave Y → Wave X Wave X → Wave W → Wave Y → Wave Z Wave Z → Wave Y → Wave W → Wave X

Wave X → Wave W → Wave Y → Wave Z

Which of these objects would most likely cause a sound wave? a drill laying on its side a nail stuck into a piece of wood a hammer hitting a metal cup a wrench locked in place around a bolt

a hammer hitting a metal cup

Which refers to the density of the medium's particles at the compression of a sound wave? amplitude pitch volume wavelength

amplitude

A high amplitude sound wave can best be compared to a short hill. tall hill. tightly coiled spring. stretched-out spring.

tightly coiled spring.

Sound waves move the fastest through which medium? water at high temperatures water at low temperatures air at high temperatures air at low temperatures

water at high temperatures

In sound waves, the distance between compressions is called the wavelength. What is the distance between rarefactions called? speed frequency amplitude wavelength

wavelength
