Wave properties of electrons

Postby huntercrespo1C » Fri Apr 20, 2018 12:59 pm

Can someone please explain to be the difference between constructive and destructive waves and what exactly it means?

Constructive interference is waves in phase and they have the same sign for amplitude and thus when the waves meet they line up at the crests and create a wave with higher amplitude. Destructive interference is waves out of phase and the crest of one wave meets the trough of another, essentially disrupting the entire thing and creating a wave with lower amplitude. Constructive interference has the same signs and destructive interference has opposite signs and wave interference can only occur when there are two waves interacting. Wave interference is relevant because it shows wave properties of electrons.

This site has super helpful pictures!

Basically, if the peaks and troughs of 2 waves happen at the same time, it'll create larger peaks and larger troughs because the energies combine. However, if the peak of one wave happens during the trough of another, the upward and downward energies will cancel out for a smaller wave, or even nonexistent if the amplitudes are equal
