What is an example of a longitudinal wave?

• Sound

• Radio wave

• Water wave

• Light

What happens at the compressions in a longitudinal wave?

• Particles are stationary

• Particles move in circles

• Particles are furthest apart

• Particles are closest together

Which of the following is not a characteristic of longitudinal waves?

• Compressions and rarefactions occur

• Sound is an example

• Particles move parallel to energy

• Particles move perpendicular to energy

What is the role of the drum skin in producing sound?

• It absorbs sound waves

• It reflects sound waves

• It vibrates to create sound waves

• It does not affect sound production

How do particles move in transverse waves?

• Perpendicular to the wave direction

• Parallel to the wave direction

• In a zigzag pattern

• They do not move

What is the movement of energy in a wave compared to the slinky in the examples?

• Neither moves

• Only slinky moves

• Both slinky and energy move

• Only energy moves
