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?
only through the air
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
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.
Which of the following best explains why vibrations from a thick rubber band make a lower-pitched sound than vibrations from a thin rubber band?
The thick rubber band is shorter.
The thick rubber band is longer.
The thick rubber band moves faster.
The thick rubber band moves slower.
A sound wave with low amplitude produces which type of sound?
