1
4
How does sound usually travel?
carrying air in one direction
through the air in all directions
through the air in one direction
carrying air in all directions
5
How does sound travel through air?
The wave gains energy from the moving molecules.
The wave carries a molecule until it hits another one.
The wave carries molecules away from the sound.
The wave's energy causes molecules to move back and forth
6
What does sound do to your eardrum?
inflates it
vibrates it
rotates it
elevates it
7
Why does sound travel faster in solids than gases?
atoms are smaller in solids
atoms are closer together in solids
atoms are larger in solids
atoms are farther apart in solids
8
How does carpeting help reduce sound?
it refracts the sound
it reflects the sound
it amplifies the sound
it absorbs the sound
9
Which part of a wave shows how loud it is?
wavelength
magnitude
amplitude
frequency
10
Which substance will sound travel the fastest through?
air
water
outer space
steel
11
Sound is a longitudinal wave that travels as
a patter of up and down movement
a wave without a medium
a series of compressions and rarefactions
a series of compressions
12
How does a whistle make noise when you blow it?
the whistle vibrates
air is absorbed by the whistle
the air inside heats up and expands
the air in the whistle vibrates
13
How do all musical instruments make sound?
they create vibrations
they send sound waves in one direction
two objects strike each other
they make sound waves with the same amplitude
14
What effects the speed of sound?
the type of motion that creates it
the material it travels through
the amplitude of the sound waves
the wavelength of the disturbance
15
A high pitch sound has
a low amplitude
a low frequency
a high amplitude
a high frequency
16
Why doesn't sound travel in space?
gravity is too strong
space is too cold
energy from the Sun is too powerful
matter is too far apart
