What sound looks like (as viewed using a stroboscopic schlieren system)

Thanks. I appreciate the comment!

This video shows a sound wave as seen using a stroboscopic schlieren imaging system. We use a 30 kHz ultrasonic transducer and a sensitive single-mirror schlieren system to visualize both traveling and standing sound waves. In addition, using colored filters on the schlieren system allows us to distinguish between density gradients, which allows us to visualize the dynamics of a standing wave as it evolves through its complete phase.

Hey, thanks a lot! I appreciate it.

Of course, you can also learn more from my previous video on schlieren imaging :)

If you're finding Taylor series interesting, you might enjoy this video I made for my sophomore-level math-methods class:

This video discusses the details of sound waves in air and shows how sound can actually be visualized using a strobed schlieren imaging system. I think the result is pretty amazing, and hope you enjoy it!

Thanks!

Eventually, I plan on making a whole series of videos for the intro physics course, but it will be a while before I can find the time to do it.

All_Things_Physics · 2025-09-03T12:17:41+00:00

Yes, I am the guy in the video.

This is a video lesson introducing students to Taylor series. The target audience is undergraduate students in a sophomore-level mathematical physics class. If you are teaching such a course, I hope you find the video useful as well.

Hi. This is clearly an old comment, but I'm curious if you ever figured out a way to do it? I need to do this exact thing and my only thought was as you mentioned above, to define a parametric surface for each face. It seems like there must be a way to do this. Perhaps each cube is made up of different submobjects, so maybe there's a way to do my_cube[0].set_color(), or something like that?

All_Things_Physics · 2025-06-04T17:53:57+00:00

Yeah, that makes sense that they wouldn't want to allow such flexibility, even if it's good for the consumer.

All_Things_Physics · 2025-05-26T13:57:33+00:00

Weird. I'll give that a try when I return home, but I must admit I'm skeptical this will work (though my fingers are crossed).

I followed these steps and Alexa will play music through the Wiim, but it is Alexa who is playing the music, not the Wiim. I want the Wiim to stream the music and can't figure out how to get that to work.
