Definition: When light is obstructed by an object and the wave front is changed, interference occurs between components of the altered wave front. The pattern formed by interference is called the diffraction pattern. Many components are designed to yield very specific diffraction effects (diffractive optics, gratings). Other components attempt to counteract this process to determine more information about the obstructing medium (electronic imaging).
Definition: light rays scattered and change direction when they are passed through a small hole or close to an opaque surface.
