G7 Chapter 14: Waves, Light and Sound

When a wave moves from point X to point Y

• energy only moves from point X to point Y.

• energy and matter move from point X to point Y.

• energy and matter move from point Y to point X.

  D.

• energy moves from point X to point Y and matter moves from point Y

  to point X.
