The complementary wave and particle character of quantum objects (or quantons) was pointed out by Niels Bohr. This wave-particle duality, in the context of the two-slit experiment, is here described not just as two extreme cases of wave and particle characteristics, but in terms of quantitative measures of these characteristics, known to follow a duality relation. A very simple and intuitive derivation of a closely related duality relation is presented, which should be understandable to the introductory student.

How can interfering light waves transport particle characteristics? Up to now it was supposed that wave-particle duality was a quantum mechanical phenomenon which was not accessible to any classical explanation. The present article is disproving this assumption, by showing o n e single case which is entirely subject to a classical explanation: Photons in vacuum. The suggested classical explanation of wave-particle duality is simple, and it is deriving directly from special relativity: The particle characteristics are transported directly from A to B, without any intermediate of spacetime, because the interval is zero. The observed wave is a sort of placeholder in our spacetime.

The need of understanding and teaching about wave-particle duality if light with gets more and more apparent in the background of the attention of modern physics. As early as the beginning of twentieth Century, Einstein dared to "deny" the development of a very perfect light electromagnetic theory, so that the quantum of light can be developed. In 1924, De Broglie put forward wave-particle duality if light to other micro particles and the concept of matter wave, pointed out that all micro particle has wave-particle duality. This is a very abstract concept for students, most college physics teaching all lack of demonstration about particle duality of light. The present article aims to contribute to demonstrate the wave-particle duality of light at the same time using a simple way based on fiber optical tweezers. It is hoped that useful lesson can be absorbed so that students can deepen the understanding of the particle and wave properties of light. To complement the demonstration experiment for this attribute light has momentum.
