Sound Waves

A sound is first produced by making something_______. The sound then travels through a _______ to reach the ears, which are parts of the body that allow for sounds to be heard.

Put the steps in order from 1 to 4 to describe how sound waves travel. Energy is passed from particle to particle: Energy reaches the ear, which allows for hearing: A sound wave is produced when an object vibrates: Energy from the object is transferred to particles around the vibrating object:

Compression

Wavelength

Amplitude

Rarefaction

Which sound wave features are being described? Number of wavelengths --------------------------- : time Distance traveled --------------------: time

Which factors affect the speed of sound? type and volume of medium temperature and type of medium volume and temperature of medium

Complete the passage. Sound waves and some earthquake waves are_______waves. Ocean, light, and other earthquake waves are_________waves.

Which features do sound waves have that ocean and light waves do not? Check all that apply. compressions rarefactions amplitude wavelength crests frequency speed

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.

How many complete wavelengths are present in the sound wave shown? 1 2 4 6

As elevation increases, temperature decreases. At which elevation will sound travel fastest? 500 meters 1,000 meters 1,500 meters 2,000 meters

Sound waves are created when something is caused to_______.

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

When sound is created, it travels to the ear through a________. compression. medium. rarefaction. surface.

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.

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

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

A student takes notes in class. Sound Waves I. Created by a vibration A. Vibration: something that causes air molecules to move back and forth quickly and steadily II. Move through a medium A. Solid B. Liquid C. Gas Which line of her notes contains an error? I I A II B II C

The_________of a wave is the density of the medium's particles at the compression of the wave.

In which part of the wave are the particles of the medium closer together? rarefactions compressions solids liquids

Which statement can be made about waves A and B? Wave A has a lower amplitude than Wave B. Wave A has a higher amplitude than Wave B. Wave A has a lower frequency than Wave B. Wave A has a higher frequency than Wave B.

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

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

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

Sound waves move the most slowly through________.

Waves move fastest in__________. low-temperature gases. low-temperature solids. high-temperature gases. high-temperature solids.

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.

Wave A is being decreased in temperature, and Wave B is moving from a liquid to a gas medium. Which statement can be made about both waves? They will speed up. They will increase the density of their medium. They will slow down. They will decrease the density of their medium.

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

A wave will go faster through a liquid at _________temperatures.
