To the left we display a wave passing through two openings, or slits, and forming an interference pattern on the right.
To the right we have a real interference pattern from electrons, produced by Dr. Akira Tonomura. For some more information, please see https://www.physics.unlv.edu/~jeffery/astro/quantum/qm_double_slit.html for more information.
