Single Slit interference

The nature of spacematter as a fluid under trochoidal motives of an arbitrary nature has many interesting phenomenon. The notion of viscous corpusclles as one designation of the possible behaviours of the spacematter fluid was used to explain a possible mechanism for sticky vorticular structures which have dynamic centres that are not independent. That is, the structures exist not as conglomerates of independent dynamic motoves but as a compound structure of a complex motive, often existent due to external and internal motives.

It was suggeted that for such a structure to transform into "independent" viscous corpuscles a greaeter transformative cataltic motive was implied, and this led to the notion of a catalytic constant or Plancks constant.

However the variation in relative motives, it was suggested was in fact a fundamental apprehension of density, combining and obscuring the behaviours of Gravity and levity. thus wihi these compound or conglomerate structures much remains to be explored, but they certainly are not distinct from their environments even when distinguished perceptually.

I pass on to light as an exam[le of a spacematter fluid with a particular structure of motives. this structure is shown to have relative densities(of motives) by Newton's Prism diffraction of it, and perhaps to be conglomerate rather than compound. In the course of experimental exploration the phenomenon of single and duble slit interference were observed. The analogy with wave behaviour was correctly drawn, but the experimenters fell into some noteable discord regarding the metaphysical nature of light.

At the time the complexity of fluid mechanics was beyond their arts of logs Analogos reasoning, and religious dogma obscured the investigation.

the matter may be resolved simply by adopting the fluid dynamic paradigm . We notice that a stream of fluid on interacting with a more viscous material is bent or encouraged round the object. this is called the Coananda effect. Thus it becomes clear that the nature of a so called slit is of significance to the passage of any fluid including "light' . We expect and find both in the single and double slit experiments that th edges of the slits contribute greatly to the observed behaviours.

In addition to the Coananda effect one has the contribution of absorption and reemission, which may be a significant part of the Coananda effect in any case. This absorption and reemission provide sources of light from the 2 edges of the slit. This provides a similar and scaled source of dual interfering sources as in the dual slit experiment.

The coananda effect is seen also in laminar flows past an object perpendicular to the flow. The stream is ent around the edges into the fluid behind the object. Tis fluid is disturbed by the in-curling stream, which is curled by the higher potential motive in the less motile fluid, However, in addition the fluid body moves as a whole and interacts with the streams at the other edges also undergoing the Coananda effect.

This is an unstable dynamic and this shows by the development of vortices and vortex shedding.

The development of this instability is observable and explainable, but totally not expected in the Potential or scalar descriptions of flow by Euler, and Navier Stokes, and criticised by D' Alembert as impossible "mathematically". This means that the mathematical description was not consistent with observations, the differential solution was 0. It was ot realized that vortices would have a differential solution of 0 till Helmholtz .

The solution Helmholtz described mathematically involved two counter rotating vortices. While the vortices were temporarily stable their relative positions were not, they circled each other. In a stream ine situation this was akin to generating a sinusoidal disturbance or a trigonmetric one at least. The disturbance was damped by the flow but as the flow diminished the sinusoidal disturbance grew, leading to the familir oscillatory pattern seen in most test tanks, called vortex shedding.

this vortex shedding is characterisitic of fluid behaviour and is perceived as diffraction of the incident wave front, Just because he wave front conception is orthogonal to the stream conception does not make the actual process different. In fact the stream concept is a good analogue of the particulate theory that describes this phenomenon.

The interference pattern dud to the Coanabda effect is as structured as the dual slit effect because the vortices obey a trigonometric law. Because of this "interference patterns of disturbances are the norm.

the more eneral solution for the Euler and Navier Stokes equations will be Trochoidal because of this,
