The bending of a wave.

Explanation:
Bending of a wave happens when the wave crosses into a new material and changes speed, which makes it change direction at the boundary. This change in direction is called refraction. A familiar example is light bending as it enters water from air, making a straw look bent in the glass. Reflection would be the wave bouncing off a surface, absorption is when the material takes in the wave’s energy, and diffraction is bending around edges or through openings rather than at a boundary between media.
