The sound is basically a vibration that travels through the air that can be heard when it gets to the ear. While you were in school, you might have discovered the different sound patterns and how to measure how high or low it is. Do you believe you have a proper understanding of sound waves? Take up the physics test below and refresh your memory.

• 1.

### The lower the frequency, the _____________ the pitch of the sound.

• A.

Higher

• B.

Lower

• C.

Quieter

• D.

Louder

B. Lower
Explanation
The lower the frequency of a sound, the lower it will be in pitch. This means that the sound will have a lower tone and be perceived as deeper. The frequency of a sound wave is directly related to its pitch, so a lower frequency corresponds to a lower sound.

Rate this question:

• 2.

### The higher the amplitude, the __________________ the sound.

• A.

Higher

• B.

Lower

• C.

Quieter

• D.

Louder

D. Louder
Explanation
The higher the amplitude of a sound, the louder it is. Amplitude refers to the maximum displacement of a sound wave from its equilibrium position. A larger amplitude means that the sound wave has a greater intensity or energy, resulting in a louder sound.

Rate this question:

• 3.

### The Hertz (Hz) is the unit of measure for which wave property?

• A.

Frequency

• B.

Wavelength

• C.

Amplitude

• D.

Speed

A. Frequency
Explanation
The Hertz (Hz) is the unit of measure for frequency. Frequency refers to the number of complete cycles or oscillations of a wave that occur in one second. It is commonly used to describe the pitch of sound waves or the rate at which electromagnetic waves (such as radio waves or light waves) oscillate. The higher the frequency, the more cycles occur in a given time period, resulting in a higher pitch or energy level.

Rate this question:

• 4.

### If the frequency of the wave is lowered, what happens to the speed of the sound wave?

• A.

Sound wave speeds up

• B.

Sound wave slows down

• C.

Sound wave speed does not change

• D.

All of the above

C. Sound wave speed does not change
Explanation
When the frequency of a wave is lowered, it does not affect the speed of the sound wave. The speed of a sound wave is determined by the medium through which it travels, such as air or water, and is not dependent on the frequency. So, regardless of whether the frequency is high or low, the speed of the sound wave remains constant.

Rate this question:

• 5.

### Sound waves are what type of waves?

• A.

A longitudinal wave

• B.

A transverse wave

• C.

A surface wave

• D.

A tidal wave

A. A longitudinal wave
Explanation
Sound waves are classified as longitudinal waves because they propagate by compressing and expanding the medium in the same direction as the wave travels. In other words, the particles of the medium vibrate parallel to the direction of wave propagation. This is in contrast to transverse waves, where the particles of the medium vibrate perpendicular to the direction of wave propagation. Surface waves and tidal waves, on the other hand, refer to specific types of waves that occur at the interface between different mediums (such as water and air) or due to the gravitational pull of the moon, respectively.

Rate this question:

• 6.

### How loud are noises in space?

• A.

Really loud, nothing out there to stop the sound waves

• B.

Very quiet with a few noises, almost like walking in the forest.

• C.

It's space, there are no sounds in space.

• D.

Never been there, I wouldn't know.

C. It's space, there are no sounds in space.
Explanation
This answer is correct because in space, there is no air or medium for sound waves to travel through. Therefore, sound cannot be transmitted, and thus, there are no sounds in space.

Rate this question:

• 7.

### Sound waves are longitudinal waves which have _________________ and rarefactions.

• A.

Crests

• B.

Compressions

• C.

Troughs

• D.

None of the above

B. Compressions
Explanation
Sound waves are longitudinal waves that consist of compressions and rarefactions. Compressions are areas where the particles in the medium are pushed close together, resulting in a higher pressure and density. Rarefactions, on the other hand, are areas where the particles are spread apart, resulting in a lower pressure and density. These alternating regions of compressions and rarefactions create the characteristic pattern of a sound wave. Therefore, the correct answer is compressions.

Rate this question:

• 8.

### Sound does not travel in space because

• A.

Too many asteroids

• B.

Too dark

• C.

No air, so there is no medium to travel through.

• D.

It's too vast

C. No air, so there is no medium to travel through.
Explanation
Sound requires a medium, such as air or water, to travel through. In space, there is a vacuum, which means there is no air or any other medium for sound waves to propagate. Therefore, sound cannot travel in space.

Rate this question:

• 9.

### Another term for a sound reflection off of a wall or other object through which a sound wave cannot pass is

• A.

Amplitude

• B.

Echo

• C.

Reverb

• D.

Vibration

B. Echo
Explanation
An echo refers to the reflection of a sound wave off of a surface, such as a wall, that does not allow the sound to pass through. When a sound wave encounters a surface that is reflective, it bounces back, creating a distinct repetition of the original sound. This phenomenon is commonly known as an echo.

Rate this question:

• 10.

### If a sound wave travels 5 meters in 0.01567 seconds, what is the speed of the sound wave?

• A.

319 m/s

• B.

0.07835 m/s

• C.

4.984 m/s

• D.

5.01567 m/s

A. 319 m/s
Explanation
The speed of a sound wave can be calculated by dividing the distance traveled by the time taken. In this case, the sound wave travels 5 meters in 0.01567 seconds. Dividing 5 by 0.01567 gives us a speed of approximately 319 m/s.
