Waves Quiz

What is the primary characteristic that distinguishes transverse waves from longitudinal waves?

• Particles move perpendicular to wave direction
• Particles move parallel to wave direction
• Waves do not transfer energy
• Waves do not have amplitude

Which of the following best describes amplitude?

• The distance between consecutive wave peaks
• The maximum distance from equilibrium to peak or trough
• The time taken for one complete wave to pass
• The number of waves passing a point per second

If the frequency of a wave increases, what happens to its wavelength?

• It increases
• It decreases
• It remains the same
• It becomes zero

What phenomenon explains the change in pitch of an ambulance siren as it approaches and then moves away from an observer?

• Reflection
• Refraction
• The Doppler Effect
• Interference

In which type of wave do particles move parallel to the direction of wave travel?

• Transverse waves
• Longitudinal waves
• Surface waves
• Electromagnetic waves

What is a wavefront?

• The maximum height of a wave
• An imaginary line connecting points in the same phase
• The distance between two consecutive waves
• The speed of the wave

What happens to waves when they enter a denser medium?

• They speed up and bend away from the normal
• They slow down and bend towards the normal
• They reflect back
• They disappear

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