Speed of sound waves travel depends on the
distance between the vibration source and the receiver.
type of material through which the sound travels.
size of the object making the sound.
type of device making the sound.
A longitudinal wave can travel through
solids only
liquids only
gas, liquids, and solids
gas and vacuum only
Sound waves travel the fastest through
rock
seawater
space
atmosphere
As a sound wave travels through the air and hits a glass of water. How will the sound wave change?
It will travel faster.
It will travel slower.
It will become louder.
It will become quieter.
Sound is able to travel faster in solids than in air because
solid molecules are closer together than air
solid molecules are more easily moved than air
solid molecules are moving faster than air
solid molecules are larger than air molecules
A whistle produces a sound because blowing air in the whistle causes
the whistle material to shake.
the air inside the whistle to vibrate.
the air to be absorbed by the whistle.
the air in the whistle to heat up and expand.
Sound travels as a
wave without a medium.
series of compression only.
pattern of up and down vibrations.
pattern of compressions and rarefactions.

Can sound travel in space?
Yes, of course it can.
No, sound needs a medium to travel through.
What can't sound travel through?
Solid
Liquid
Gas
Vacuum
Typically, sound will travel fastest in a
Solid
Liquid
Gas
Why can't we hear explosions in space?
Space is a vacuum, there isn't matter for sound to travel through
The sound waves gain too much energy.
The sound waves bounce back and forth until they lose energy.
Particles in space absorb the sound waves.
- How is sound produced?
Sound is produced by slapping of my hands.
Sound is produced by vibrations of object in a medium.
Sound is produced by a sound producer.
Sound is produced by how long and soft you speak.
2. How does a sound wave travel ?
Sound waves travels perpendicular to the direction of wave travel.
Sound waves travels from one end to another end by reflection.
Sound waves travels by displacement of particles in a medium, through a series of compressions and rarefactions.
Sound waves cannot travel in vacuum.
