Particle motion in Transverse and Longitudinal wave gif

I found this GIF a few years back and have no idea where it originally came from. I did not create it but wanted to use it in my classroom so I made it into a video file that I could find easily.

Edit: Thanks to a comment, I think I found the site where it originated:

From that site: "The following animations were created using a modifed version of the Mathematica® Notebook " Sound Waves" by Mats Bengtsson."
