How do musical instruments produce sound?
By pitching sounds
Through air molecules
Through vibrations
By hiding wavelengths
What would best replace the number 2 on the chart?
Making impact
Mouth position
Pushing air
Vibrating strings
How does this instrument produce sound?
Electrical currents are made when the bow and string meet and produce sound.
The fusion with the strings makes the sound.
As the bow goes across the strings, it causes vibrations in the violin.
Wind energy is used to cause the vibrations between the bow and the string.
Which picture shows a compression wave?
The molecules of gases are far apart; therefore, —
sound travels more quickly through gases
sound travels more slowly through gases
How many meters per second will sound travel at 60 degrees Celsius?
(a)
What are the three types of matter through which sound travels?
Televisions
Solids
Liquids
Air
Gases
Sounds travel slowest through -
silver
gold
water
oxygen
Why does sound travel faster in stainless steel than in gold?
The molecules are farther apart.
The molecules are closer together.
The molecules of solids are close together so -
sound travels more quickly through solids
sound travels more slowly through solids
sound does not travel through solids
Sound travels slowest through -
gold

Fresh water
Sea water
Which can be caused by a vibrating tuning fork?
Hearing loss
Power outage
Death of insects
Ripples in water
What is transferred when vibrations are transmitted from air molecule to air molecule?
Weight
Pitch
Volume
Energy
Which phrase best describes compression in a wave?
