Pop Flashcard 4.3

Front

What is a transverse wave?

Back

A wave in which particles move perpendicular to the direction of energy transfer.

Front

What is a longitudinal wave?

Back

A wave in which particles move parallel to the direction of energy transfer.

Front

How does energy transfer in a longitudinal wave?

Back

Energy is transferred through the vibration of particles in a direction parallel to the wave's motion.

Front

What are compressions in a longitudinal wave?

Back

Regions where particles are close together.

Front

What are rarefactions in a longitudinal wave?

Back

Regions where particles are spread apart.

Front

Can longitudinal waves travel through a vacuum?

Back

No, longitudinal waves require a medium (like air or water) to travel.

Front

Can transverse waves travel through a vacuum?

Back

Yes, transverse waves can travel through a vacuum, such as light waves.

Front

What type of wave is a sound wave?

Back

A longitudinal wave.

Front

What type of wave is observed when a rope moves up and down?

Back

A transverse wave.

Front

What is the main difference between transverse and longitudinal waves?

Back

Transverse waves move perpendicular to energy transfer; longitudinal waves move parallel.
