A Proof that Diffraction Grating Experimental Wavelength Conclusions are in Error

Photons have been shown in this author’s prior papers to be spinning, washer shaped, atomic sized particles which are single electric field corpuscles that move orthogonally to the washer face at the local speed of light. Thus, light has no frequency and is not a wave. Perhaps one of the major arguments in favor of light being a wave is that diffraction grating experiments accurately identify the source of the emitted photons. A fundamental assumption in the analysis involving these experiments is that the incident light at the grating slits  is a coherent wave. It will be shown in this work that this assumption cannot be valid. However, in spite of this result, and in spite of light being particle shaped and not a wave, it is briefly outlined in this work and shown in an upcoming paper that the conclusions which are drawn concerning source identities are correct. Thus, these spectroscopy experiments have great value even though the wavelengths they indicate do not exist.
