In the introduction, the authors quote textbooks which state that the standard two-slit experiment can not be done because the scale of the experiment would be on too small of a scale. For electrons which are excited across a voltage of 50-400 Volts, calculate the range of the deBroglie wavelengths, and use this fact to comment on the authors' comment. (b) Historically, it was for electrons which the first interference was observed for matt
