4.2    THE PHOTONS INTERFERENCE AND DIFFRACTION

      We will see now how this particles exhibit interference and diffraction behaviors.

      It is proposed that photons can be aligned to form a train of photons:

Each photon is linked to the next by the same equilibrium phenomenon described for the positrin and negatrin that constitutes a single photon. A positrin is always followed by a negatrin. The electric and magnetic forces maintains a strong link.

We will see now how these trains of photons satisfy the Huygens phenomenon. We must consider two trains separated by a distance d and emitted simultaneously in a certain angle θ such that they join at a certain “large” distance.

The next schema describes the phenomenon:

It can be observed that depending on the angle θ the trains will join at a certain large distance with different phases.

In certain angles they will join in phase what means that charges of the same sign of each train are confronted (this happens for example at θ = 0). In this case the repulsive electric force will maintain them apart and they behave separately as ordinary beams of light. They can be reflected or exhibit photons' absorption or emission phenomena.

In other angles the trains will join out of phase what means that opposite charges of each train are confronted. In this case there is an attractive force between the trains.

It is proposed that when the trains join out of phase they form a very compacted array of a couple of trains that cannot be separated and can pass trough common materials (between the atoms) in a way that no reflections or photons' absorption or emission effects can be observed

This is the case that corresponds to the called “destructive interference”.

We can deduce from the figure that:

When  sinθ = nλ/d            n=0,1,2,3,…

“constructive interference” exists.

When  sinθ = (n + ½)λ/d              n=0,1,2,3,…

“destructive interference” exists.

Note that if a beam of light passes trough a fine slit some trains interact with the borders and are deviated in all directions and the same phenomenon applies.
