A reflection is a flip of an object over a line. Let's look at two very common reflections: a horizontal reflection and a vertical reflection. Notice the colored vertices for each of the triangles. The line of reflection is equidistant from both red points, blue points, and green points.

Diffuse reflection is the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection. An illuminated ideal diffuse reflecting surface will have equal luminance from all directions which lie in the half-space adjacent to the surface.
