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
