Unit 2 Energy Review

What are waves?

• Particles that move perpendicular to the direction of energy transfer

• Particles that move parallel to the direction of energy transfer

• Particles that move in a circular motion

• Particles that do not move

Which type of wave requires a medium to travel through?

• Transverse waves

• Longitudinal waves

• Both transverse and longitudinal waves

• Neither transverse nor longitudinal waves

What type of wave are ocean waves?

• Transverse waves

• Longitudinal waves

• Both transverse and longitudinal waves

• Neither transverse nor longitudinal waves

In a transverse wave, how do the particles move?

• Parallel to the direction of energy transfer

• In a circular motion

• Perpendicular to the direction of energy transfer

• Back and forth in the same direction as the wave

What type of wave are sound waves?

• Transverse waves

• Longitudinal waves

• Both transverse and longitudinal waves

• Neither transverse nor longitudinal waves

What are compressions in a longitudinal wave?

• Particles that are closer together

• Particles that are farther apart

• Particles that do not move

• Particles that move in a circular motion

What are rarefactions in a longitudinal wave?

• Particles that are closer together

• Particles that are farther apart

• Particles that do not move

• Particles that move in a circular motion

Can longitudinal waves move through solids, liquids, and gases?

• Yes, only through solids

• Yes, only through liquids

• Yes, only through gases

• Yes, through solids, liquids, and gases

What is the direction of vibration in a longitudinal wave?

• Parallel to the direction of energy transfer

• In a circular motion

• Perpendicular to the direction of energy transfer

• Back and forth in the same direction as the wave

What is the direction of wave propagation in a transverse wave?

• Parallel to the direction of energy transfer

• In a circular motion

• Perpendicular to the direction of energy transfer

• Back and forth in the same direction as the wave
