Which of the diagrams below does not accurately demonstrate the property of reflection?
D is incorrect because the angle of incidence is not equal to the angle of reflection.  The correct ray diagram for a convex surface is shown to the right.  The parallel light rays line up with a focal point on the other side of the surface.

A is the reflection from a irregular surface.  Notice that each ray has angle of incidence = angle of reflection.  The light is scattered.

B is the reflection from a concave surface.  Parallel light rays reflect through the focal point.

C is the reflection from a plane surface.  Notice that parallel light rays are reflected parallel.

The Correct Answer is D.
