We model photons as being rigid bodies. Based only on Newtonian mechanics, we simulate numerically collisions of photons and atoms. The rigid bodies used for photons are spherical and their center of mass and centroid are not coincident. Thus, each rigid body (photon) describes a cycloid (presenting amplitude, frequency and phase) as well as the DeBroglie wave. The numerical results indicate not only a predominant color for each given surface but also a time of response very similar to time spent on quantum decay.

The goal of this work is to study the behavior of light reflection and provide a mechanical resemblance of this behavior. In a laboratory , we measured the time spent from the launch of a pulse of photons and their return to the location of the emitted pulse, after colliding against the surface of an atom. In the numerical analysis, we modeled photons and atoms as being spherical and non-homogeneous rigid bodies. Due to the non-uniform internal mass distribution, the centroid and the center of mass of the photons will be shifted. While the center of mass tends to describe a straight line, the centroid tends to describe a cycloid rotating towards the center of mass. Due to the rotation of the photon, its time of return varies. The numerical results indicate times of return relatively similar to those achieved by experimental results.

We model photons as being rigid bodies. Based only on Newtonian mechanics, we
reproduce numerically the Fresnel Diffraction Experiment. In this way, a large number of rigid bodies
are thrown against a single slit. The rigid bodies used are spherical and their center of mass and
centroid are not coincident. Thus, each rigid body describes a cycloid (presenting amplitude,
frequency and phase - as well as the DeBroglie wave). The numerical results indicate a wave pattern
relatively similar to those achieved by experimental results. Different apertures and depths of the slit
were tested.
