Diffraction is a phenomenon observed with all forms of waves, including, light, sound, and water.  It involves the change in direction of waves as they pass around a barrier or through a small opening. 

An example of this is a water wave traveling behind a stationary boat near the shore.  Another example is the ringing appearance of light passing through a small hole in a sheet of paper as it is reflected off a wall.  It happens because when waves are disturbed, they create new waves of varying wavelengths and amplitudes.  The constructive and destructive addition of these new wavelengths of light produces the diffraction pattern.
