I'm preparing for an upcoming course in QM by working out of a textbook, and I've encountered a handful of conceptual questions that I'm having trouble answering. I figured it best to ask my questions in a single thread, so as not to clutter the subforum. Also, I chose the general physics subforum because it's unlikely that I'll be asking anything that may be considered advanced physics (but feel free to move the thread if need be).(adsbygoogle = window.adsbygoogle || []).push({});

To start with:

1. The wavelength of a matter wave is, of course, given by [tex]\lambda = \frac{h}{p}[/tex]. If an object has zero momentum, does its wavelength get arbitrarily large? And if so, why doesn't its wave nature dominate?

2. Let's say that a beam of electrons are moving through a single slit (with a width comparable to the wavelength of the electron). The electrons would then show upall overthe screen/detector that lay behind the single slit. Could we say that the electrons show up atallplaces on the screen at aconstantrate? Or would we only be able to speak in terms of theaveragerate of electron detection for any given region on the screen?

Any help is welcome and appreciated.
