Diffraction of Matter: Examining Bohr's Theory

[Mustafa Bayram]

Does matter (like electrons) diffract at the single slit and create an interference pattern on the screen? If it's not why? Isn't that violation of Bohr's Theory?

 

[Dale]

You need two slits for an interference pattern

 

[Mustafa Bayram]

light does interference pattern with a single slit, but matter doesn't. What happens to Bohr's wavelength? What happens to the wave-particle duality of matter?

The single-slit pattern is often called a diffraction pattern instead of an interference pattern (although it might be more sensible to call them both self-interference patterns). In principle single-particle single-slit setups will produce a diffraction pattern, although in practice the effect may be difficult to observe.

This is simply not true.

If you set up the experiment well matter will *diffract*. And more interestingly if you do a double slit experiment with matter you can get actual interference.

It is more difficult to do with matter, but it still happens.

Yes:

For the sake of historical justice, Bohr did not discover wave mechanics. This were de Broglie and Schrödinger, who among others, helped to get rid of Bohr's ad-hoc theory, which only worked for the hydrogen atom ;-).
