Diffraction Patterns for Electrons

Postby 405289292 » Mon Oct 21, 2019 9:14 pm

I'm assuming that electrons have diffraction patterns because they have wave properties, but I just want to clarify that that is the case

Yes that's right. Using the deBroglie equation, you can see that that the wavelength of the electron is very noticeable compared to its size, compared to a baseball, whose wavelength is negligible and undetectable. All waves will have diffraction patterns, so when the electron is acting as a wave, then the patterns will arise.

The diffraction patterns that electrons create does show electron wave like properties. In the double slit experiment it was shown that electrons behave as waves. When electrons passed through slits and hit a screen, dark and bright lines showed up. The bright spots were formed from electrons having constructive interference and the dark spots were formed from destructive interference. The diffraction patterns resulting from the interference proved electrons behave like waves.

Yes, they do. They have a small enough mass where theycan exhibit wave like properties via the De Broglie equation.
