  • 2. 

    Sound begins with matter.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Sound is a form of energy that is produced by the vibration of matter. When an object vibrates, it creates sound waves that travel through a medium, such as air or water. These sound waves then reach our ears, allowing us to perceive sound. Therefore, it can be concluded that sound does indeed begin with matter, making the answer "True".

    Rate this question:

  • 3. 

    The same note played at the same loudness on different instruments sound the same.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Different instruments have unique characteristics that affect the way they produce sound. While playing the same note at the same loudness may result in similar pitch, the timbre or quality of the sound will vary depending on the instrument. Each instrument has its own unique set of harmonics and overtones that contribute to its distinct sound. Therefore, playing the same note on different instruments will not sound exactly the same.

    Rate this question:

  • 4. 

    Sound travels in __________.

    Correct Answer
    waves.
    Waves
    waves
    Waves.
    Explanation
    Sound is a form of energy that travels in waves. These waves are created when an object vibrates, causing the surrounding air particles to vibrate as well. These vibrations then travel through the air as waves, which our ears detect as sound. Therefore, the correct answer is "waves."

    Rate this question:

  • 5. 

    Check the ones that are true and leave the ones that are false.

    • The Doppler effect was discovered by Albert Einstein.

    • Bats and dolphins use echolocation to find their food.

    • Quality makes sound louder.

    Correct Answer
    A. Bats and dolphins use echolocation to find their food.
    Explanation
    This statement is true. Bats and dolphins use echolocation to find their food. Echolocation is a biological sonar system that these animals use to navigate and locate objects in their environment. They emit high-frequency sound waves and listen for the echoes that bounce back, allowing them to determine the location, distance, and movement of objects around them. This ability is crucial for their survival and hunting success.

  • 6. 

    The part of a sound wave where molecules bunch together is called ________________.

    Correct Answer
    Compression
    compression
    Compression.
    compression.
    Explanation
    The part of a sound wave where molecules bunch together is called compression.

    Rate this question:

  • 7. 

    Sound travels in waves just like _____________.

    Correct Answer
    Light.
    Light
    light.
    light
    Explanation
    Sound travels in waves just like light. Both sound and light are forms of energy that travel in waves, although they differ in the medium through which they propagate. Sound waves require a medium such as air, water, or solids to travel, while light waves can travel through a vacuum. Both sound and light waves exhibit properties such as wavelength, frequency, and amplitude, and can be reflected, refracted, and diffracted. Therefore, the comparison of sound waves to light waves is appropriate.

    Rate this question:

  • 8. 

    The part of a sound wave when molecules spread apart is ______________.

    Correct Answer
    Rarefaction
    rarefaction
    Rarefaction.
    rarefaction.
    Explanation
    The correct answer is "Rarefaction." Rarefaction refers to the part of a sound wave where molecules spread apart.

    Rate this question:

  • 9. 

    What is the Doppler effect?

    • When somebody bakes a cake.

    • When the sound can effect different types of buildings and knock them down.

    • When the roar of a siren is louder coming toward you then going away from you.

    Correct Answer
    A. When the roar of a siren is louder coming toward you then going away from you.
    Explanation
    The Doppler effect refers to the change in frequency or pitch of a sound wave when the source of the sound is moving relative to the observer. As the source moves closer to the observer, the sound waves are compressed, resulting in a higher frequency and a perceived increase in volume. Conversely, as the source moves away from the observer, the sound waves are stretched, resulting in a lower frequency and a perceived decrease in volume. Therefore, the statement "When the roar of a siren is louder coming toward you then going away from you" accurately describes the Doppler effect.

    What does sound travel the best through?

    • Jell-O

    • Liquids

    • Solids

    • Gases

    Correct Answer
    A. Solids
    Explanation
    Sound travels the best through solids because they have a higher density and a more compact structure compared to liquids and gases. The particles in solids are closely packed, allowing sound waves to easily propagate through them. Liquids and gases, on the other hand, have less dense and more loosely arranged particles, which results in a less efficient transmission of sound.
