Sound waves are unable to pass through the two chambers.
Sound waves pass faster through chamber 1 than chamber 2.
Sound waves pass through the two chambers at the same speed.
3
All the following demonstrate sound except a -
girl holding a jar to a wall
student blowing into a trumpet
spaceship roaring in outer space
boy putting his ear down on a railroad track
4
Which letter represents compression?
A
C
B
D
5
Sound is a mechanical energy that is transmitted in the form of
Heat
Electrons
Light
Waves
6
In which order must the bottles be placed to produce sounds from lowest to highest pitch?
B, A, D, C
C, D, A, B
A, B, C, D
D, A, B, C
7
Which letter represents rarefaction?
B
A
D
C
8
If people were molecules, sound would travel faster in picture -
A. Separated molecules transmit sound more efficiently.
A. Tightly packed molecules transmit sound more efficiently.
B. Separated molecules transmit sound more efficiently.
B. Tightly packed molecules transmit sound more efficiently.
9
Sound travels fastest through matter that is -
Gas
Solid
Liquid
10
As the length of the ruler hanging over the table's edge
increases
the -
faster the vibrations and the lower the pitch
slower the vibrations and the lower the pitch
slower the vibrations and the higher the pitch
faster the vibrations and the higher the pitch
11
This letter represents the measure of the frequency of these compression waves.
D
A
C
B
12
The greater the frequency of a sound wave, the -
louder the sound
softer the sound
higher the pitch
lower the pitch
13
Which letter represents a complete wavelength?
B
A
C
D
14
If the frequency of sound waves decreases, then the pitch becomes -
louder
higher
lower
quieter
15
How could you make a musical instrument’s pitch sound higher?
Play it louder so the sound waves travel farther.
Increase the frequency of the sound waves it produces.
Decrease the frequency of the sound waves it produces.
Play it softer so the sound waves do not travel as far.
16
What is the relationship between frequency and pitch?
When the frequency is higher, the pitch is lower.
When the frequency is lower, the pitch is higher.
When the frequency is higher, the pitch is higher.
Frequency has no effect on pitch.
17
It is inaccurate for movies to attach sound to spaceships travelling in space because -
Sound waves travel where there is matter to transmit them
Frequency of any sound becomes too high for humans to hear
Sound waves would spread out so that they couldn’t be heard
18
Woodwind, string, percussion, and brass are different kinds of musical instruments. They are -
played by blowing into a part
played by producing vibrations
made completely out of wood
made completely out of metal
19

C
B
D
A
20
In the pan pipe above, which numbered pipe would have the lowest pitch and why?
Pipe 8 has the lowest pitch; it has the most vibrations
Pipe 8 has the lowest pitch; it has the least vibrations
Pipe 1 has the lowest pitch; it has the most vibrations
Pipe 1 has the lowest pitch; it has the least vibrations
21

True
False
22
The following are examples of factors that affect the pitch of a vibrating object
except
–
how shiny a bell is when someone rings it
how tight a rubber band is when someone plucks it
the amount of water a bottle has in it when someone taps it
the length of a tube when someone blows into it
