5th Grade Sound Quiz

1. Which is an example of a vibration?

Like a cat running as fast as it can

A light going on and off

The feeling you get after you've been playing too long

Up and down movement of a motor

An example of a vibration is the up and down movement of a motor. Vibration refers to the rapid back and forth motion of an object or a system. In this case, the motor is likely to have an oscillating or reciprocating motion, causing it to move up and down. This movement creates a vibration, which is a common characteristic of motors and other mechanical devices.

2. How are sounds created?

Ocean waves

Electricity

Speakers

Waves

Something vibrating

Sounds are created when something vibrates. When an object vibrates, it causes the surrounding air particles to vibrate as well. These vibrations then travel through the air as sound waves, which our ears can detect. This is how we are able to hear different sounds in our environment.

3. A higher pitched sound has higher ______________.

starts with H

The term "Hertz" refers to the unit of measurement used to quantify the frequency of a sound wave. Frequency is the number of cycles or vibrations that occur within a given period of time. In the context of sound, a higher pitched sound is produced by a sound wave with a higher frequency, meaning it has more cycles or vibrations per second. Therefore, a higher pitched sound has a higher frequency, which is measured in Hertz.

4. What does a sound wave look like?

5. How are longitudinal waves different than transverse waves.

Longitudinal waves are perpendicular to the direction they move

Longitudinal waves are bigger

Longitudinal waves move parallel to the direction the wave moves

Longitudinal waves are smaller

Longitudinal waves are different from transverse waves because they move parallel to the direction of the wave. In transverse waves, the motion of the particles is perpendicular to the direction of the wave. Therefore, the correct answer is that longitudinal waves move parallel to the direction the wave moves.

Explanation

Longitudinal waves are different from transverse waves because they move parallel to the direction of the wave. In transverse waves, the motion of the particles is perpendicular to the direction of the wave. Therefore, the correct answer is that longitudinal waves move parallel to the direction the wave moves.

6. If you move a rope up and down you see_____________ waves.

Transverse

Longitudinal

Compression

Electromagnetic

When you move a rope up and down, you will see transverse waves. Transverse waves are characterized by the particles of the medium oscillating perpendicular to the direction of the wave propagation. In the case of the rope, as you move it up and down, the particles of the rope move perpendicular to the direction in which the wave travels, creating transverse waves.

When you move a rope up and down, you will see transverse waves. Transverse waves are characterized by the particles of the medium oscillating perpendicular to the direction of the wave propagation. In the case of the rope, as you move it up and down, the particles of the rope move perpendicular to the direction in which the wave travels, creating transverse waves.

7. If a sound is super loud it has a large ______________.

Distance between waves/ wavelength

Strength waves/ amplitude

Number of vibrations/ hertz

Pitch

Acoustics

The correct answer is "strength waves/ amplitude." When a sound is super loud, it means that the sound waves have a high amplitude or strength. Amplitude refers to the maximum displacement of the particles in a medium as the sound wave passes through it. So, a larger amplitude indicates a louder sound. The other options, such as distance between waves (wavelength), number of vibrations (hertz), pitch, and acoustics, are not directly related to the loudness of a sound.
