Diffraction and Water

Postby Anisha Chandra 1K » Sat Oct 12, 2019 2:34 pm

I didn't really understand when Dr. Lavelle was talking about diffraction and connecting that to how waves work with water. Could someone please explain that? Thanks!

The diffraction patterns that are produced by electrons are similar to those of water waves when they enter two holes in a barrier to create separate wave fronts that combine and interact with each other. These waves can be formed from constructive interference (waves in phase) and destructive interference (waves out of phase).

I believe he was just trying to give a visual example. When you drop two rocks in the water next to each other, it is easy to see how the waves (ripples in the water) interact with each other and form both constructive and destructive interference.

Are diffractions only analyzed through the peaks of waves?

I think so because in order to analyze the interference patterns, you can look at the peaks of the waves to see if they are getting narrower, larger, etc.
