Flashcard on Sound Waves

Front

Why do molecules in solids and liquids transmit sound more quickly than in gases?

Back

Molecules in solids and liquids are closer together.

Front

What is the function of the cochlea in the ear?

Back

It turns vibrations into nerve impulses.

Front

What are the two areas in longitudinal waves?

Back

Compression and rarefaction.

Front

What happens when a speaker vibrates outward?

Back

Molecules are pushed together to form a compression.

Front

What is the speed of sound in cork?

Back

500 m/s.

Front

Define sound waves.

Back

Sound waves are longitudinal waves that are created by vibrating objects and propagate through a medium.

Front

What is the difference between compression and rarefaction in sound waves?

Back

Compression is the region where molecules are close together, while rarefaction is the region where molecules are spread apart.

Front

How does temperature affect the speed of sound?

Back

The speed of sound increases with an increase in temperature.

Front

What medium transmits sound the fastest?

Back

Sound travels fastest in solids.

Front

What is the role of the eardrum in hearing?

Back

The eardrum vibrates in response to sound waves, transmitting these vibrations to the inner ear.
