Testing a mechanical model of photon:
An excentric sphere describing a cycloid
presents mass and wave behavior
Goal:
- Use Newtonian Mechanics to model known
behaviors of Light:
- Diffraction Experiment
- Color Experiment
- Quantum decay Experiment
Testing the proposed photon model:
Single slit diffraction experiment
Testing the proposed photon model:
Experimental result observed in the bulkhead
Testing the proposed photon model:

Testing the proposed photon model:
An excentric sphere collides against the single slit
Testing the proposed photon model:
The collisions are Elastic and Newtonian
Testing the proposed photon model:
Kinematics
Testing the proposed photon model:
Excentric sphere
colliding against the slit
Conservative Energy
and Momentum
Dynamics
Testing the proposed photon model:
After a large number of excentric spheres has
been thrown against the single slit, what is the
expected pattern in the bulkhead?
Results
Results
The results indicate a pattern relatively similar
to the experimental results
Results
When we reduce the
aperture of the slit ,the
widths of the fringes
reduce as well, indicating a
clear correlation with the
single slit experiment
Colors
The CIE1931 Color Model
(Smith, T., Guild, J., "The C.I.E. colorimetric standards and their use".
Transactions of the Optical Society 33 (3): 73–134, 1931)

source
Metameric colors:
The same perceptual color
can obtained by different
combinations of
monochromatic light
sources
Red source
Blue source
So... modeling colors using Newtonian mechanics...
The same collision system used in diffraction is used
to model colors...
After each collision the frequency changes...
The output frequency depends on the light source and
the material...
Examples of input and output frequencies
Input frequency
Red (425THz)

Quantum decay
Sample (Petroleum
derivative called Neosine)
Photodetectors
Pulsed Laser
(100ns)
Quantum decay of Neosine (Petroleum derivative)
obtained from Bacia de Campos (Brazil)
Numerical results (pink) and
Experimental results (dark blue)
The quantum decay depends on the photon’s exit angle.
The time to return to the photodetector depends on the
tangent of this angle.

Future work:
Based on Black Body Radiation and known melting
process (water), estimate the photon’s melting point
and its thermodynamical properties
(~273K)
(~4000K)
Light and water: similar mechanisms?
