Wave properties of electron diffraction

[dana hu 1B]

Hello! Does anyone have any insight into the wave properties of electron diffraction and how its caused?
thank you

So electron diffraction is a phenomenon observed when a beam of electrons passes through a very small opening, and as a result of constructive/destructive interference (a property of waves only), a pattern of electron density is generated that shows high/low presence in unexpected places. ie, because of the wave properties, the beam of electrons doesn't just flow through the small opening in a straight line to the other side as one might expect, but goes off at angles to the sides. This is a property also observed with light waves, and help prove the wave properties of matter. I hope this helps!

Adding on to rabbi, constructive interference is when two waves 'collide' and increase in intensity (matching peaks and troughs), and destructive interference is when two waves 'collide' and decrease in intensity (differing peaks and troughs). Since a beam of electrons demonstrate this property, it can be used to prove the wave-particle duality of light.

Hope this helps!

One of the UA's in her review session posted this which I thought was helpful in understanding the concept

Hi! If you wanted any further clarification on the topic, there are tons of youtube videos if you search 'double slit experiment' :) hope this helps!

Can someone explain how the wave properties being in phase or out of phase correspond to the electrons in an atom?
