### wave properties of electrons

can someone explain how/why we know that electrons have wavelike properties? I know he related wave properties to electrons but I couldn't understand the conclusion that electrons have wavelike properties based on diffraction patterns and such

### Re: wave properties of electrons

To test that electrons have wave-like properties, they treated an electron like it was light. Essentially, they shot an electron through 2 slits. If the electron behaved like a single particle, it would only make a single spot through one of the slits. However, the electron did not do this, it made a spot through both slits (a diffraction pattern), showing that electrons behave as waves.

Here's a picture showing the experiment: https://upload.wikimedia.org/wikipedia/ ... it.svg.png

Hope this helps!
