What might happen to an object sitting on top of a speaker if loud music is played through the speaker?
Absolutely nothing would happen to the object.
The object could move due to the vibrations of the sound.
The object could appear a different color because the sound is absorbed.
The object could stop the sound from being transmitted out of the speaker because sound cannot travel through a solid.
How does sound travel?
in waves
only through the air
through magnets
as thermal energy
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.
Which of these waves would produce a high pitch sound?
Low frequency wave
High frequency wave
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.
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.
If you pull a guitar string tighter, what will happen to the sound it creates?
The pitch will become higher because the string will vibrate more quickly.
The pitch will become lower because the string will vibrate more slowly.
The sound will get louder because more energy will be in the string.
The sound will get quieter because less energy will be in the string.
A sound wave with low amplitude produces which type of sound?
High
Low
Loud
Soft
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
This diagram shows two different ways to represent longitudinal waves.
Which letter corresponds to rarefaction in the waves?
Z
X
W
Y
What type of waves might experience rarefaction?
rope rays
x-rays
Sound Waves
infrared rays
Two sound waves of different frequencies interfere and produce a resulting waveform shown with four points (W, X, Y, and Z) marked on the new wave.
At which point will the sound be the loudest ?
W
X
Y
Z
The students in the diagram are communicating with the cans and string.
Which is the most likely explanation of how the students can hear and communicate using the objects?
A Mechanical Wave transfers sound through the string
sound bounces off the can and echoes
sound travels through the string as an electromagnetic wave
Transverse wave transfers sound through rope
The diagram shows a research vessel using sonar to map the ocean floor.
Upon which basic behavior of sound waves does this technology depend?
absorption
compression
reflection
refraction
Through which medium is it impossible to transmit sound waves?
space
rock
air
water
A boy has a cork on his fishing line in a lake. His brother throws a rock in the lake near where he is fishing, and the waves created from the rock splashing cause the boy's cork to bob up and down for over a minute. What is the medium for the waves in this scenario?
the cork
the water
the rock
the fishing line
