Practice Question

1. What type of wave are sound waves?

Longitudinal

2. List the main parts of the human ear involved in hearing.

Ear canal, eardrum, ear bones (ossicles), cochlea, auditory nerve.

3. Describe the role of the eardrum in hearing.

The eardrum vibrates in response to incoming sound waves, transmitting these vibrations to the ear bones (ossicles) in the middle ear.

4. Define the typical frequency range of human hearing.

20Hz to 20,000Hz

5. Explain how sound waves are converted into vibrations in solids.

Sound waves cause particles in a medium to vibrate. When these waves encounter a solid, they induce vibrations in the solid’s particles at the same frequency.
