Unit 8.2 Quiz 4

Which graph represents a sound with the highest pitch?

• A

• B

• C

• D

Answer explanation

Graph D represents a sound with the highest pitch because it shows the highest frequency of sound waves. Higher frequencies correspond to higher pitches, making D the correct choice.

Which graph represents the highest (loudest) volume?

• A

• B

• C

• D

Answer explanation

Graph C represents the highest volume as it shows the tallest peaks compared to graphs A, B, and D, indicating greater sound intensity.

Which graph represents the sound with the lowest pitch and lowest volume?

• A

• B

• C

• D

Answer explanation

Graph C represents the sound with the lowest pitch and lowest volume, as it shows a longer wavelength (indicating lower frequency) and a smaller amplitude (indicating lower volume) compared to the other graphs.

Which graph represents the loudest sound?

• A

• B

• C

• D

Answer explanation

Graph B represents the loudest sound as it shows the highest amplitude compared to the other graphs. Higher amplitude indicates a louder sound, making B the correct choice.

A sound wave is produced in a metal cylinder by striking one end. Which of the following occurs as the wave travels along the cylinder?

• It transfers matter.

• It transfers energy.

• Its frequency increases.

• Its amplitude increases.

Answer explanation

As the sound wave travels through the metal cylinder, it transfers energy from one particle to another, allowing the wave to propagate. It does not transfer matter, and its frequency and amplitude remain constant.

Sound waves cannot carry energy through:

• air.

• a mirror.

• empty space.

• water.

Answer explanation

Sound waves require a medium to travel through, such as air, water, or solids. They cannot propagate in empty space, as there are no particles to transmit the energy of the sound waves.

Drummers use energy when they hit their drums. Which of the following best describes what happens to this energy?

• Some of the energy is converted into sound and some is converted into heat.

• All of the energy is destroyed.

• Some of the energy is converted into sound and some is destroyed.

• All of the energy is converted into sound.

Answer explanation

When drummers hit their drums, some energy is transformed into sound, creating the music we hear, while some energy dissipates as heat due to friction and vibration, making the correct choice: 'Some of the energy is converted into sound and some is converted into heat.'
