Abstract
An easy experiment about the cancelation of the total internal reflection condition is shown. Reducing the air gap between a curved surface and an acrylic-air interface it is possible to eliminate the interface allowing the cancellation of the total reflection condition at a small area. This fact becomes clear in the form of a beam light in the transmitted direction as well as a shadow line in the reflected beam.
