Flashcard on Waves

Front

What produces sound?

Back

Sound is produced by the vibration of a medium.

Front

How is music converted into electrical signals in the brain?

Back

Music makes the eardrum vibrate. The eardrum’s vibrations are then transmitted to the inner ear, which converts the vibrations into electrical signals that are sent to the brain.

Front

What type of wave is visible light?

Back

Visible light is an electromagnetic wave.

Front

What is an area of rarefaction in a sound wave?

Back

An area of rarefaction is where the particles of the medium are spread apart.

Front

How do Wave A and Wave B compare in terms of frequency?

Back

Wave A has a lower frequency than Wave B.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through a medium or space.

Front

What are mechanical waves?

Back

Mechanical waves require a medium to travel through, such as sound waves.

Front

What are electromagnetic waves?

Back

Electromagnetic waves do not require a medium and can travel through a vacuum, such as light waves.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the medium's particles move parallel to the direction of the wave, while in transverse waves, they move perpendicular.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).
