This question is modern physics from the waves and particles chapter: An electron beam strikes a barrier with a single narrow slit, and the electron flux – number of electrons per unit time per unit area – detected at the very center of the resulting intensity pattern is F_1. Next, two more identical slits are opened equidistant on either side of the first and equally “illuminated” by the beam. What wil be the flux at the very center now? Does your answer imply that ore than three times as many electrons pass through three slits than through one? Why or why not?
