refraction
Refraction means the bending of waves. It is frequently mistaken for reflection, which is the bouncing of waves off of a surface. Refraction happens because waves (such as light waves) travel at different speeds through different materials--as the wave passes from one material, or medium, to another, it bends as it either speeds up or slows down.
