Sound Waves

Multiple Choice

Which best describes vibration?

• the distance traveled per unit in time

• the action of moving back and forth quickly and steadily

• the distance between one compression and the compression next to it

• the action of moving through a material or substance

Multiple Choice

Which of these would most likely cause a sound wave?

• cookies baking

• milk standing in the bottle

• a spoon hitting the side of a bowl while mixing

• butter melting

Multiple Choice

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

Multiple Choice

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.

Multiple Choice

In which part of the wave are the particles of the medium closer together?

• rarefactions

• compressions

• solids

• liquids

Multiple Choice

In sound waves, the distance between compressions is called the wavelength.

What is the distance between rarefactions called?

• speed

• frequency

• amplitude

• wavelength

Multiple Choice

Which refers to the density of the medium’s particles at the compression of a sound wave?

• amplitude

• pitch

• volume

• wavelength

Multiple Choice

A high amplitude sound wave can best be compared to a

• short hill.

• tall hill.

• tightly coiled spring.

• stretched-out spring.

Multiple Choice

What is the frequency of this wave?

• 1

• 2

• 3

• 4

Multiple Choice

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

Multiple Choice

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

Multiple Choice

Sound waves move the slowest through which medium?

• water

• ice

• air

• wood

Multiple Choice

Sound waves move the fastest through which medium?

• water at high temperatures

• water at low temperatures

• air at high temperatures

• air at low temperatures

Multiple Choice

Waves move fastest in

• low-temperature gases.

• low-temperature solids.

• high-temperature gases.

• high-temperature solids.

Multiple Choice

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.
