In Discussing the Electron Double- Slit Experiment, We Studied a Graph

Multiple Choice

In discussing the electron double- slit experiment, we studied a graph of the extended wave pattern formed on the screen by each electron's matter field. Did this graph show a single electron's matter field just before, or just after, the electron strikes the screen, and why?

A) This is the matter field just after impact, because each electron actually spreads out over a large region and strikes all over this region, in a wave pattern.
B) This is the matter field just before impact; after impact the matter field transforms into two distinct parts, with one part appearing on the screen directly behind each slit.
C) This is the matter field just before impact; after impact, the electron acquires a definite velocity.
D) This is the matter field just before impact; after impact the matter field collapses into a small region around the impact.
E) This is the matter field just after impact, because the electron can strike the screen at a wide variety of specific places, and these places form a field pattern.
