Total questions: 20
Worksheet time: 14mins
What is transported by a wave?
air
energy
matter
particles
How does sound travel?
in waves
only through the air
through magnets
as thermal energy
Which TWO of the following statements about sound are NOT true?
Sound is produced through vibrations.
Sound travels in waves.
Sound can travel through outer space
Sound waves can bounce off of objects to create an echo.
Sound waves can only travel through the air.
Sound waves can travel through all three states of matter. Which of the following best explains why sound travels most quickly through a solid?
Solids always produce an echo, which makes the sound seem louder to the human ear.
Only solids allow the vibrations to travel from one atom (particle) to another.
In solids, the atoms (particles) are closest together, which allows the vibrations to travel rapidly from one to another through the object.
Sound does not travel quickly through a solid. It travels most rapidly through a gas.
Why can't sound travel through outer space?
There is almost no matter in outer space, so the vibrations have no way to travel through the atmosphere. There is nothing to carry the sound waves through space.
Sound actually travels very quickly through outer space because there is no matter to slow down the sound waves.
There are too many planets and stars in outer space that absorb all of the sound waves, so they cannot travel to the human ear.
Because outer space is a "vacuum," the vibrations are irregular and travel in too many directions for us to detect the sound.
If you pluck a guitar string, it vibrates and creates a sound. In order to stop the sound, you could...
blow on the string.
pluck a different string.
place your hand on the string to stop the vibration.
pluck the same string again.
Which of these waves would produce a high pitch sound?
Low frequency wave
High frequency wave
The speed of a sound wave
Amplitude
Wavelength
Volume
Frequency
What determines the pitch of a sound?
The amount of energy used to create the vibration
The wavelength of the sound wave.
The volume of the sound.
The frequency of the vibrations.
A sound wave with low amplitude produces which type of sound?
High
Low
Loud
Soft
ex. police car siren sounding lower pitch after the car passes
The diagram shows a cartoon of a sound wave produced while a student is speaking.
What happens to the sound wave when the student speaks louder?
The amplitude increases
the wavelength will double
the speed will increase
the amplitude will decrease
