Longitudinal and Transverse Waves

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 wave 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.
