Properties of electron being Particle v Wave

Postby Rohan Kubba Dis 4B » Sat Oct 12, 2019 1:47 pm

I understand that electrons have a duality of having particle-like properties as well as wave-like properties, however, what are the exact examples or properties or that make each side valid? (Atomic Spectra, Photoelectric effect, etc.)

The photoelectric effect (i.e. shining light on a metal and finding the threshold energy of an electron) was used as strong evidence that light is a photon with certain energy/frequency. This proved that electromagnetic radiation including electrons behaved in a particle like matter rather than a wave. However, when electrons were emitted to a single crystal of Nickel, scientists observed a diffraction pattern which illustrated that electrons must have wave like properties as well. Therefore, the wave-particle duality was accepted.

Also, diffraction patterns results from constructive and destructive interference. Since diffraction patterns result from interacting waves, electrons must have wavelike properties in addition to particlelike properties.

What is the difference between an electron's particle-like and wave-like properties?
