What is a medium?
States of Matter (solid, liquid, gas)
100
What is pitch?
How high or low a sound is
100
What is frequency?
Number of wavelengths that determine pitch (how high or low a sound is)
100
Which number represents a wavelength?
1
200
What is the best medium for sound to travel?
Any solid mediums
200
What does amplitude determine?
volume
200
High pitch sound have (more/less) waves per second
more
200
Low pitch sound waves have (more/less) waves per second
less
200
If a compression wave have a high frequency then it has a (high/low) pitch
high
300
If a compression wave has a low frequency, then it has a (high/low) pitch
low
300
What does it mean to transmit sound?
To produce sound or vibrations
300
How do musical instruments create sound?
through vibrations
300
Which image represents a sound wave?
Bottom: longitudinal wave
300
What are the three types of matter that sound can be transferred through?
Solid, liquid, gas
400
Molecules in a solid are close together/dense. This means that sound will travel...(faster/slower)
faster
400
Choose all the objects that will make sound transfer the fastest.
Wooden table. Balloon
Pond Oxygen
Concrete. Propane tank
wooden table and concrete
400
What is one reason why a guitar can produce different pitches?
The body is hollow, the size of the strings, how tight the string is
400
Why is there no sound in space?
There are no mediums for sound to travel through.
There is no air or matter in space
400
Molecules in the air are far apart/less dense. This means that sound travels...(faster/slower)
slower
500
Why does sound travel slower through air?
Because the molecules are farther apart
500
What occurs when you place a vibrating tuning fork in water? Does it make ripples, a splash, or nothing occurs?
ripples
500
Sound is a form of what?
energy
500
To produce sound you start with (mechanical/sound) energy, that transfers to (mechanical/sound) energy.
1. mechanical 2. sound
500
What is transferred when sound transmits through the air?
a. volume
b. pitch
c. energy
energy
