3
Which part of a wave shows how loud it is?
wavelength
magnitude
frequency

4
How do all musical instruments make sound?
they create vibrations
they make sound waves with the same amplitude
they send sound waves in one direction
two objects strike each other
5
What does sound do to your eardrum?
rotates it
vibrates it
elevates it
inflates it
6
Why does sound travel faster in solids than gases?
atoms are larger in solids
atoms are closer together in solids
atoms are farther apart in solids
atoms are smaller in solids
7
Sound is a longitudinal wave that travels as
a series of compressions and rarefactions
a wave without a medium
a patter of up and down movement
a series of compressions
8
How does sound usually travel?
through the air in all directions
carrying air in all directions
through the air in one direction
carrying air in one direction
9
Why doesn't sound travel in space?

matter is too far apart
space is too cold
10
Which part of the diagram is the amplitude?
3
4
1

11
How does sound travel through air?
The wave gains energy from the moving molecules.
The wave's energy causes molecules to move back and forth
The wave carries a molecule until it hits another one.
The wave carries molecules away from the sound.
12
How is an echo created?
sound is reflected
sound is refracted
sound is scattered
sound is absorbed
13
Which substance will sound travel the fastest through?
air
steel
outer space
water
14
A high pitch sound has
a low frequency
a high frequency
a low amplitude
a high amplitude
15
How does a whistle make noise when you blow it?
air is absorbed by the whistle
the air inside heats up and expands
the whistle vibrates
the air in the whistle vibrates
16
How does carpeting help reduce sound?
it absorbs the sound
it refracts the sound
it amplifies the sound
it reflects the sound
