Diffraction Youtubes

We observed diffraction of laser light off the surface of a set of staples from a Swingline stapler. We also compared that to regular reflection from a small mirror.

But there are many other places where diffraction occurs, many different sources of light that diffracts. I have several YouTubes up that show diffraction in action. Look at my diffraction playlist.

I also like a diffraction YouTube from Saint Mary's Univ. up in Canada, especially from about the 0:25 mark.
