How is the use of soundwaves helpful to this whale?
It makes the water warmer
It helps the whale locate its food
It makes it easier to obtain oxygen
It signals the fish to move out of the whale's path
2
What conclusions can you draw about sound waves passing through the shown chambers?
Sound waves are unable to pass through the two chambers.
Sound waves pass faster through chamber 2 than chamber 1.
Sound waves pass through the two chambers at the same speed.
Sound waves pass faster through chamber 1 than chamber 2.
3
How could you make a musical instrument’s pitch sound higher?
Increase the frequency of the sound waves it produces.
Play it softer so the sound waves do not travel as far.
Play it louder so the sound waves travel farther.
Decrease the frequency of the sound waves it produces.
4
Which letter represents compression?
C
B
A
D
5
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 higher the pitch
slower the vibrations and the lower the pitch
faster the vibrations and the higher the pitch
6
In the pan pipe above, which numbered pipe would have the lowest pitch and why?
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
Pipe 8 has the lowest pitch; it has the most vibrations
7
Sound travels fastest through matter that is -
Gas
Liquid
Solid
8
All the following demonstrate sound except a -
boy putting his ear down on a railroad track
student blowing into a trumpet
girl holding a jar to a wall
spaceship roaring in outer space
9
In which order must the bottles be placed to produce sounds from lowest to highest pitch?
D, A, B, C
A, B, C, D
C, D, A, B
B, A, D, C
10
If the frequency of sound waves decreases, then the pitch becomes -
lower
higher
louder
quieter
11
Woodwind, string, percussion, and brass are different kinds of musical instruments. They are -
made completely out of wood
played by blowing into a part
made completely out of metal
played by producing vibrations
12
Which of the following are not likely to use echolocation?
whales
bats
humans
dolphins
13
It is inaccurate for movies to attach sound to spaceships travelling in space because -
Frequency of any sound becomes too high for humans to hear
Sound waves would spread out so that they couldn’t be heard
Sound waves travel where there is matter to transmit them
14
This letter represents the measure of the frequency of these compression waves.
B
D
A
C
15
What is the relationship between frequency and pitch?
When the frequency is higher, the pitch is lower.
Frequency has no effect on pitch.
When the frequency is lower, the pitch is higher.
When the frequency is higher, the pitch is higher.
16
Which straw will make the highest pitch?
C
A
D
B
17
The greater the frequency of a sound wave, the -
softer the sound
louder the sound
higher the pitch
lower the pitch
