Unit 3 Practice Test (Science)

Some points are marked on a wave, as shown in the diagram to the right. The wavelength is the distance between which points?

• 1 and 3
• 2 and 6
• 4 and 5
• 1 and 7

A wave is shown in the diagram below. Which best describes the wave?

• The wavelength ends at the crest.
• The amplitude equals the wavelength.
• The amplitude of the crest equals the amplitude of the trough.
• The wavelength is the height of the crest plus the height of the trough.

Which wave has the greatest amplitude?

• A
• B
• C
• D

Scientists measured the amplitude of ocean waves during a storm. Which part of the diagram shows the amplitude of a wave?

• 1
• 2
• 3
• 4

As a wavelength decreases, the crest of the wave

• Become wider
• Become shorter
• Get closer together
• Get farther apart

As the wavelength increases, the frequency

• Decreases
• Increases
• Remains the same
• Increases and then decreases

Which diagram shows the wave with the highest frequency?

• 
• 
• 
• 

Which diagram best represents particle movement in a transverse wave?

• 
• 
• 
• 

In transverse waves, particles move how?

• Up and down (perpendicular to the wave movement)
• Back and forth (parallel to the wave movement)
• Not at all

Which statement best explains the difference between longitudinal and transverse waves?

• Longitudinal waves have troughs, while transverse waves have crests.
• Longitudinal waves produce energy, while transverse waves consume energy.
• Particles in longitudinal waves travel towards a force, while particles in transverse waves travel away from a force.
• Particles in longitudinal waves travel in the direction of the wave, while particles in transverse waves travel perpendicular to the wave.
