In a transverse wave, how does the matter move relative to the direction the wave travels?

In a transverse wave, how does the matter move relative to the direction the wave travels?

• A. Up and down
• B. Along the direction of travel
• C. Side to side
• D. In circles

Answer: (A)

Transverse waves transfer energy in one direction while the medium moves perpendicular to that direction. For a wave traveling along a rope, the rope’s particles move up and down as the wave passes, so the motion is perpendicular to the direction the wave travels. That up-and-down movement is what defines a transverse wave. The other descriptions would fit different kinds of wave motion (longitudinal would be along the travel direction, circular motion isn’t typical here), so up and down is the correct way to describe the medium’s movement.
