sound
pitch
frequency
wavelength
3
When frequency increases, what else goes up?
wavelength
volume
pitch
amplitude
4
The independent variable is:
what you measure or observe
things you keep the same
the thing you make different or change
5

radiant
mechanical
solar
electrical
10
What causes sound?
frequency
vibrations
molecules
sound
11
Amplitude is directly related to the ____________of sound.
pitch
volume
frequency
12
What is the relationship between vibration and pitch?
the faster the vibration, the lower the pitch
the softer the vibration, the higher the pitch
the slower the vibration, the higher the pitch
the faster the vibration, the higher the pitch
13
Which of these makes the sound with the slowest vibration?
A
B
C
D
14
The greater the frequency of a sound wave, the ________ the pitch.
softer
lower
louder
higher
15
How do musical instruments produce sound?
through air molecules
by hiding wavelengths
through vibrations
by pitching sounds
16
In a sound with a High pitch:
wavelengths are the same as low pitch
wavelengths are shorter than low pitched
wavelengths cannot be compared to a low pitched sound
wavelengths are longer than in a low pitched sound
17
How is sound transmitted?
electrons
light
heat
waves
18
Sound travels the slowest in a gas because:
there are no molecules
the molecules are packed tightly together
the molecules are spread out
the molecules are kind of close together
19
If someone makes a sound with a high pitch:
the wavelengths are the same as in a low pitched sound.
the wavelengths are shorter than in a low pitched sound.
the wavelengths are exactly the same
the wavelengths cannot be compared.
20

water
milk
gold
oxygen
21
In which liquid will sound travel the fastest?
D) Sea Water
C) Fresh Water
A) Cannot be determined
B) Water Vapor
22
In the wave in the picture, what do we call the areas that are pressed together?
wavelength
compression
rarefaction
frequency
23
The part of the wave where the molecules are spread out is called:
rarefaction
direction of travel
compression
wavelength
