REFLECTION



               -Reflection is the change in direction of a signal at an

               interface between two different media so that the

               signal returns into the medium from which it


               originated.


               -The angle of incidence is equivalent to the angle of

               reflection







               DIFFRACTION



               -When light waves pass near a barrier, they tend to

               bend around that barrier and spread at oblique angles
