Sound that DOES NOT bounce back to you
The Doppler effect occurs when
The waves are moving like the ripples in a pond from a rock
A moving object is emitting sound continuously.
There is a rainbow present in the sky.
The waves are really distorted in the front where the sound is and not in the back after the object moves away
Sound travels through waves called

Which part of your ear is the final structure that sends the message to your brain that you've heard a sound?
the outermost part of your ear
the vibrating eardrum
the hammer, anvil, and stirrup located in your middle ear
the hair-like structures in the cochlea that are attached to nerve cells
Why does sound travel faster through a solid object than in the air?
The atoms in the solid object are farther apart than the atoms in the air.
The atoms in the solid object are closer together than the atoms in the air.
The atoms are smaller in the solid object than the atoms in the air.
The atoms are larger in the solid object than the atoms in the air.
This illustration shows a sound wave traveling from a tuning fork through a medium. What parts of the wave are labeled X and Y?
X represents the compressions; Y represents the rarefactions.
X represents the rarefactions; Y represents the compressions.
X represents the compressions; Y represents the wavelength.
X represents the rarefactions; Y represents the wavelength.
Look at this illustration of a wave. Which points on the wave are the trough and the crest?
Point W is a trough; Point Y is a crest.
Point Y is a trough; Point W is a crest.
Point Y is a trough; Point X is a crest.
Point W is a trough; Point Z is a crest.
Mattie wanted to measure the speed of sound through different materials. Mattie planned to use the table shown to record data. Through which material will Mattie most likely find that sound travels the fastest?
Balloon filled with air
Tank filled with water
Block of aluminum
Tank filled with oil
A fifth-grade student fastened a piece of cardboard to his bicycle wheel so that the spokes would cause the card to vibrate. When the student rode the bike fast, the student heard a high pitch. When the student rode the bike slowly, the student heard a low pitch. Which best explains why the student heard both high and low pitches from the cardboard?
The vibrations were faster when the student rode slowly.
The vibrations were slower when the student rode faster.
The cardboard vibrated at the same speed.
The cardboard vibrated at different speeds.
When a guitar string is strummed, it produces sound by making________.
heat
electricity
vibrations
light
If all the waves were measured for a period of 5 seconds, which wave had the highest frequency?
The speed of a sound wave depends on the medium through which it travels. The table shows the speed of sound waves through different media. The greatest increase in the speed of a sound wave would result from the transition between which two media?
the air into the glass
the glass into the aluminum
aluminum into the water
water into the iron
Sound waves can pass through all of these except___________.
air
steel
water
a vacuum
An echo is a sound wave that has been________.
Absorbed
Refracted
Scattered
Reflected
How does sound usually travel?
An object vibrates, and those vibrations travel through the air in one direction as transverse waves.
An object vibrates, and those vibrations carry air in one direction as longitudinal waves.
An object vibrates, and those vibrations travel through the air in all directions as longitudinal waves.
An object vibrates, and those vibrations carry air in all directions as transverse waves.

A
B
C
D
The volume of a sound depends on the amplitude of the sound waves. The lower the amplitude of a sound wave, the quieter the sound. Which of the following sound waves illustrates the quietest sound?
The charts below show sound waves from a musical instrument. In which way is the sound wave in Chart 1 different from the sound wave in Chart 2?
it has a higher pitch
it has a lower volume
it has a lower frequency
it has a greater amplitude
