Single-Electron Double-Slit Experiment
An electron beam directed at a double-slit apparatus produces an interference pattern on a distant screen. If the beam’s intensity is reduced so that only one electron passes through the apparatus at a time, which of the following describes the pattern observed on the screen after a large number of electrons have passed?
A
Random dots with no discernible pattern
B
A single broad band in the center of the screen
C
Two distinct bands corresponding to each slit
D
An interference pattern identical to the original beam
