Wave Interactions

What is absorption in the context of wave behavior?

• The reflection of energy by a wave back into the medium

• The transfer of energy by a wave to the medium through which it travels

• The bending of a wave as it passes around an edge or through an opening

• The creation of a new wave when two or more waves overlap
