Lenard confirms Newton's particle structure of light; consequently, the diffraction effect of light is a particle effect. When a laser beam diameter is smaller than the diameter of the aperture, and the beam enters the aperture, no diffraction effect is formed unless the intensity of the laser beam contacts the aperture edge. The optic particles that contact the aperture edge activate the aperture edge atoms forming an aperture edge effect that re-directs the photons which enter the aperture to only the intensity areas of the diffraction pattern (fig 34) without involving an ether or wave interference. In the small aperture diffraction effect, a node (small dark circle) can be formed at the center of the diffraction pattern (fig 2) which represents a complete aperture edge effect. As the aperture diameter is increased, at a specific aperture diameter, only an intensity is formed at the center of the diffraction pattern which depicts the formation of a partial aperture edge effect that does not redirect the optic particles to the center of the diffraction pattern. In a razor edge diffraction effect, the edge effect occurs close to the razor edge. Furthermore, in the large aperture diffraction effect, the maximum intensity fringe produced by the partial aperture edge effect forms adjacent to the outer edge of the diffraction pattern; whereas, the maximum intensity of the complete aperture edge effect forms at the center of the diffraction pattern. The transition between the described maximum fringe positions formed by the complete and partial aperture edge effects depict the transmutation of the aperture edge effects based on the aperture diameter.
