To explain the diffraction of particles, the concept used here is that all ‘particles’ have two distinguishable but ‘interdependent’ components. The first is the ‘particle core’ and the second is its ‘wave function’. The ‘wave function’ is regarded as a circulating flow of energy around the electron’s ‘particle core’. Both the particle’s ‘spin’ and its ‘magnetic moment’ are associated with this ‘wave function’ and not with the structure of the ‘particle core’.  The electron has been chosen as an illustrative particle, but to be clear, the photon is not being viewed as being a particle, even though it has a ‘quantum’ nature.

The ‘wave length’ of the electron has been measured as being in the region of 10^-5 to 10^-7 metres, which falls within the ultra-violet region of the ‘Radiant Energy Spectrum of Light’.  What makes this concept work is that the ‘wave function’ of the electron is designated to be an ‘ultra-violet light' photon.  The behaviour of the electron is highly influenced by the uv photon surrounding its core, in that it causes the electron to behave like a ‘wave’, but if the electron’s wave function becomes separated from its core, then the electron will behave like a ‘particle’.

When electrons are despatched towards the two slits at similar velocities, they behave exactly like visible light photons, with its uv photon being diffracted at the slits, but it takes the electron's 'particle core' through with it. This process creates an electron diffraction pattern on the image recording screen, but it is a pattern of electron strikes that is shown, not a viewable ‘interference effect’ that coherent 'visible light' photons create when passing through the twin slits.

It does not matter if the electrons are despatched in batches or one at a time, the electron’s ‘particle core’ will always follow its ‘photon ring’ through the slits and record a diffraction pattern. If coherent visible photons are despatched singly towards the twin slit screen, then they will diffract, but there will be no visible interference pattern to be seen, unless the individual photon strikes are recorded and displayed on an image sensor.
 
If for any reason the electron and its uv photon become parted, then the electron will lose its ability to diffract and will pass straight through the slits, creating two vertical lines on the imaging screen.  Any attempt to ‘observe’ the passage of the electrons using a photon source will interfere with the diffraction process. Light beams of different wavelengths directed at each other are completely unaffected, simply passing through each other, so any attempt to monitor the electrons progress towards, through or after the slits using a photon source, will impinge upon the electron core and dislodge it from its uv photon, before being reflected away.

The energy of the observing photon, will determine the amount of degradation of the interference pattern on the screen. The higher the energy of the observing photon, the greater is the likelihood of the two components being completely separated and creating two vertical lines, as distinct from the electron’s particle core being marginally deflected from its original diffracting path and creating a degraded interference pattern.

Other particles with a larger core, such as the proton and the neutron, also have their own specific wave lengths, which are likewise associated with their spin and magnetic moment. So their behaviour in the twin slit experiments emulates the electron.

Because observer effect of the man made angled slits cause change of the lights flow.
