Problems with the Corpuscular Theoryas a
Mechanism

• Reflection and refraction may occur at the same
  boundary. According to the corpuscular theory,
  this would mean the presence of both repulsive
  and attractive forces at the surface of the
  medium. This was not easy to explain.

Fingerprinting using Frustrated Total Internal
Reflection
Light approaching the valleys in fingertips is
reflected normally by total internal reflection.
(The images of the valleys are bright). The
ridges of the finger tip frustrate the total
internal reflection. (The images of the ridges
are dark).
