Electron Waves Interfering
from atomic gold "slits"

real interference pattern from electrons

scattering off gold foil:

solid matter particles are wave-like,

matter particles have frequency, wavelength,

they interfere with each other

particle's wavelength not due to "jiggling"

wave function phasing in and out,

e.g. like electro(+ and -)
magnetic (North & South) field of photon

phasing from one sign to other as it propagates
